Improve list of available languages for UI l10n.

Browse Source 
Add a new tag HasGuiSupport to language file. Add it for all l10ns
that we currently ship. The po files that are unused are not currently
tagged as available, but this could be done, since the code later
checks that the translation is actually there.

This new information is used in GuiPrefs when populating the language
combox.

The new scheme implies that adding a new language is now a two-step
process:
* the language code has to be added to po/LINGUAS, as before;
* one of the entries of the lib/language file has to be selected as
  reference and be given the "HasGuiSupport true" property.

(from the git repository) and replace the existing .po with yours.
Afterwards, you should compile and optionally install LyX (check the
INSTALL file for your OS). Note that, as of LyX 2.1, it is not
necessary anymore to install anything. In order to run LyX with your
translation, change the current language in Preferences dialog or use
the appropriate LANG variable:

In order to run LyX with your translation, change the current language
in Preferences dialog or use the appropriate LANG variable:
On Linux: LANG=xx_CC lyx
On Windows, you need to change the lyx.bat file and write: set LANG=xx_CC
@ -104,6 +105,12 @@ the appropriate LANG variable:
xx stands for your language code. CC stands for your country code. So to get,
e.g., Czech, the code is "cs_CZ".
Another possibility is to use the Preferences dialog to set LyX UI to
use your language. Note that, as of LyX 2.2, a newly introduced
language will not appear in the languages combox unless it corresponds
to an entry of the lib/languages file that has a "HasGuiSupport true"
property. See this file for more details.
The most comfortable way to see your updated translation while
editing, is running (in linux) "make xx.gmo" in the po directory to
compile updated xx.po translation and then run LyX.
