fixes:
- LyX uses for a decimal alignment a multicolumn and having for a cell a multicolumn _and_ a multirow is invalid LaTeX. Therefore do not allow to set table cells to this in the dialog.
- It was impossible to unset a decimal alignment via the context menu or toolbar button.
The current code is not able to unset an environment variable, only to set it to an empty value. This patch refactors a bit the Message class and uses a new EnvChanger helper class that allows to change temporarily an environment variable and that is able to unset variables if needed.
The patch also adds new functions hasEnv and unsetEnv in environment.cpp.
Open issues:
* there may be systems where unsetenv is not available and putenv("name=") does not do the right thing;
* unsetenv may lead to leaks on some platforms.
* when using unsetenv, we may need to remove strings from the internal map that setEnv uses.

Additionally, some extra code for avoiding double undo entries has
been removed, since this is handled by grouped undo now.
Reordering citations is one case where catching "Citation undefined
on page ..." doesn't catch the need for a bibtex rerun. This patch
ensures the proper ordering is obtained in pdf output without having
to resort to closing and reopening the LyX document.
- Add a note about HTML.
- Add a note about using external files.
- Add a note about using lilypond variables and commands.
- Some corrections and nitpicks.
Fix the following bug:
When in tabular, enter "ab" in a cell. Place the cursor before "b". Hold
shift and press <right>, then (still holding shift) <right> again. On
the second <right> nothing appears to happen.
Related to #1802.

Fix bug reported on user list: the path variable here was undefined,
causing a failure when running outside the user tree. This was my
fault: when I refactored this routine, I failed to note that this
variable was now undefined.

Backported from b8648dea16.
With this new command line switch a list of modules can be loaded
unconditionally. This seems to be needed for the literate programming formats,
and it is useful to work around bug #5702 as well.
