79f11f4e7d Fix std::string docstream output error
This was made visible by aab1b145a5, since xhtml export for
lib/doc/Additional.lyx caused an exception. However, the cause for this was
already present earlier: All attempts to output a std::string to an
odocstream resulted in trying to change the encoding of the stream instead,
since there is no operator<<(odocstream &, std::string) defined, and an
implicit conversion to SetEnc happened instead.
This is fixed by making the SetEnc constructor explicit and adjusting all
code parts that did not compile anymore after that. The parts of the code
that did use the wrong output operator were the std::string version of
htmlize() from output_xhtml.cpp and all changed parts in the other .cpp files.
I also removed the std::string versions of html::htmlize() and
html::cleanAttr(), since it was difficult to see which encodings were used
with these. Now we are always explcit when using html::cleanAttr() and
html::htmlize().

ccbac353ea Fix Length::inBP()
Length::inBP() returned the wrong values for most units. I guess that this was
caused by the default case in the switch statement: It did probably exist
before the other units were added.
inBP() is now correct for all units except the font dependent ones em, ex and
mu and the percent units: For these only approximate values are returned,
since not all needed information is available.

8b86af7298 Fix LaTeX length export of big numbers, part 2 (bug #9416)
LaTeX lengths must not use scientific notation, since the + sign has a
different meaning (glue lengths). This is the GUI part of bug 9416,
on top of part 1 [59e4d16ab/lyxgit].

59e4d16ab9 Fix LaTeX length export of big numbers (bug 9416)
LaTeX lengths must not use scientific notation, since the + sign has a
different meaning (glue lengths). This is the export part of bug 9416, the GUI
part is still not fixed.

66fa801e74 Improve support for on screen length calculation
The computation of length on screen depend in particular of the computation of the size of an em. Many places of the code used to rely on the width of the M character, which is not really correct:
http://en.wikipedia.org/wiki/Em_%28typography%29

In digital typography, the best value to use is the point size of the font.

* Implement FontMetrics::em(), which returns the value in pixels of the EM unit.
 Convert code to use it.

* Introduce Length::inPixel(MetricsBase const &), which takes the textwidth and em information from the MetricsBase object. Convert code to use it.

* Fix several places where Length::inPixel is used without a proper em value.

* add mathed_font_em() helper function. It should eventually be removed like some other functions in MathSupport.

* Add dummy implementation of FontMetrics to tex2lyx for linking purposes.

2c39859575 Remove unneeded swap() (thanks Jean-Marc)
std::swap() does exactly the same thing, and avoiding code duplication is
always good.

f04c7711b0 Fix empty width support for Box inset
* InsetBox and GuiBox: Use proper empty length instead of the broken -9.99col% trick
* some slight changes to the logic of GuiBox to make sure that values are set as needed.
* lengthToWidget(): handle properly the empty length case. All the other related Qt helpers did it already, it was probably an oversight. Also set the default_unit parameter as optional (not needed in this patch actually, but I got carried away :)
* allow generating LaTeX code for an empty length, since some broken code does that.

25ff2f8e2b Improve support for empty lengths
Parse empty string as empty length
Output empty length as empty string when it makes sense (not for LaTeX strings, for example).

5014b38cb7 Add a preference option to specify the default length unit (cm or in).

269695aa5f Remove the prefence default_papersize
- This preference was used for specifying the papersize to xdvi, dvipdfm,
  dvips. However, I can't seem to see any effect on the result.

- The papersize should instead be defined in the document settings.

- The global papersize default was misused to also change the tex
  output by specifying the papersize as if it was specified in the
  document settings. This caused the same lyx document to be outputted
  differently on different pcs.

26751d83ee Move the half baked code that guesses whether to default on metric or
imperial units in only one place (instead of thousands of slightly different
copies). Functionally equivalent.

hope there are only conforming implementaions out there ;-}

5ddc612b73 Splitup Font in saner bits:
* Font::FontBits -> FontInfo
* Font::FONT_XXX -> all enums transfered to FontEnums.h and renamed to FontXxx

I've replaced Font uses with FontInfo were the language() member was not needed, basically all draw() and metrics methods. There's one problematic cases with InsetQuotes which I solved by taking the Buffer main language.
