b269eb9117 Fix a crash due to Inset**::mouse_hover_[] containing an invalid pointer to a BufferView.
Clear the mouse_hover state when closing the BufferView. Otherwise, there will be an invalid pointer stored in the Inset and crashing LyX when the Inset's destructor is called.

See also r33908, r34117, r34348, r34353, r34354, r34363 and bug #3900.

351808718d Fix another crash due to BufferView::last_inset_ being an invalid pointer.
Do not clear the mouse_hover state from anywhere else then BufferView, such that the last_inset_ pointer gets nulled. Besides, there is no reason to clear the mouse_hover state on collapsing the Inset.

See also r33908, r34117, r34348, r34353, r34354 and bug #3900.

750620765f Fix another crash due to BufferView::last_inset_ being an invalid pointer.
Now, we only want to let the last_inset_ pointer point at insets that accept the mouse_hover setting. Otherwise, the pointer is not cleared on deletion of the inset.

9c8e7429fa Fix the assertion assert introduced in r34348 which got fired when eg. deselecting an InsetCommand:
- we have to have a copy constructor in InsetCommand to clear the mouse_hover_ map and not to copy it,
- there is no need to have mouse_hover_() in the initialisation list,
- there is no need to copy the auto_open_ map.

a03faee92d There is no reason for inhibiting the symbols dialog in mathed.
The dialog only offers symbols defined in the unicodesymbols file
and they will be wrapped in \text{} when inserted in math mode,
so there is no risk that an untypesettable symbol gets inserted.

ba4e75f11c The character dialog was disabled in r30810 for solving an assertion
due to a missing buffer and because the "dialog is only useful in texted".
The problem with the buffer member has been solved since then, and while
it is true that the character dialog is not much useful in mathed, it
is the only way for coloring only parts of equations. Given that this
would also be a regression with respect to 1.6, I am re-enabling it.

6c4de0377c Fix bug #6614: Preview Other Format Button Greys Out After Preview.
getStatus() returns false for LFUN_BUFFER_VIEW when a previewing process is running. So, if this process has finished we should free the menu item. 

P.S. on windows, the item does not get disabled anyway.

71b4fd0431 This is a dummy commit for posting the real changelog for the the last
two commits. Sorry guys, I should have really gone to sleep...

r34320
In mathed, preserve the color in a proper way, such as to not interfere
with the colors normally used to represent math objects.
When changing the color of a chunk of text containing math formulas,
now the formulas are rendered on screen in the chosen color, too.

r34321
Assure that constructs such as \mathbf{a\ensuremath{b}} are correctly
rendered on screen.

c88eaf877e Changing only the shape does not always work. For example,
\mathbb{\underbar{a}} is not correctly rendered on screen.
We really have to change the font set, but not always.
This cannot be done using an "if" statement, as when
the FontSetChanger scope ends, everything is restored,
defeating our change. Thus, this has to be done in the
FontSetChanger class itself. This is easily accomplished
by introducing a boolean with a default value of true
for really changing a font set.
This will also be useful in other cases that I am discovering.

dbb5ac93ea The check for Color_math would fail if the font color is changed
in mathed, so implement a strategy which is immune to color changes.

26ebe0865c In mathed, also preserve the color when changing a font set,
otherwise symbols and font changes such as \mathit{a} are not
drawn in the selected color on screen.

f249df796f - chkconfig.ltx:
- fix the check for arabi
   - add lithuanian, mongolian and turkmen
- LaTeXConfig.lyx: introduce new section about language packages

(I purposely did not add vntex (Vietnamese) because this would be another 10 MB to download for every LyX on Windows user. The other language packages are not larger than 120 kB.)
