xft-fonts package is still required. However, on *nix there seem
to be no way to tell fontconfig to prefer our fonts instead of
others matching the requirements, so, in case of conflict, the
fontconfig files should be manually adjusted, or some existing
font package used (note that the quality of the bakoma fonts is
better than that of the xft ones). There is no such problem on
Windows where our private fonts are always preferred over the
installed ones (and I hope the same holds true for Mac).

is that we distinguish between the "Default" alignment and whatever
that default happens to be: I.e., so far as the code goes, the UI now
distinguishes LYX_ALIGN_LAYOUT from LYX_ALIGN_WHATEVER, when WHATEVER
happens to be the default. So you can explicitly force, say, left-align,
and that will stick between document classes.
* src/Paragraph.cpp:
Don't output params if alignment is the default.
* src/ParagraphParameters.cpp
Treat LYX_ALIGN_LAYOUT as its own alignment.
* src/Text2.cpp
Treat LYX_ALIGN_LAYOUT as its own alignment, and force it to be accepted
as a possible alignment.
* src/frontends/controllers/ControlParagraph.{h,cpp}
New method haveMultiParSelection().
*src/frontends/qt4/QParagraph.{h,cpp}
*src/frontends/qt4/ui/ParagraphUi.ui
UI adjustments as mentioned.

- use internal_path to prevent assert on windows (bug 3916).

* src/graphics/GraphicsConverter.cpp
(move_file, build_script): convert any path name to the local
encoding directly in the python script.
* src/support/tempname.cpp
(tempName): don't pass local 8bit encoded strings to addName as
it expects them to be utf8 encoded.
* src/ServerSocket.cpp
(ServerSocket::ServerSocket): ditto for setEnv.

acceptChanges:
* move the bulk of acceptChanges without the call to DEPM to
paragraph_funcs
copySelectionHelper:
* call this new acceptChanges
pasteParagraphList:
* use Text::setCursor(Cusor,...) instead of Text::setCursor(CursorSlice...)
in order to have DEPM invoked at the end of the insertion

- Split the language Arabic into "arabic_arabi" that uses the arabi-package and "arabic-arabtex" that uses the arabTeX-package to typeset Arabic. This is needed because both packages have some advantages over the other people need.
(This change is a consequence of a long and fruitful discussion with Mostafa, Dov, and me.)
