Added "__ = id" function as a placeholder for i18n. Module also exports it, so translatable modules will import from it.
Added "__" call to module's translatable strings.
Integrating gettext
using __ function for i18n of strings
Added "__" function to these files.

PackageEditor may have had a few corrections on __ calls.
Added "__" function to some more files.

Reinserting "__" for i18n on updated sourcefiles.
Adding messages.pot generated from our hgettext
fixing text encoding
adding some cabal deps for hgettext and pt_BR.po file
Final changes to call hgettext support.

* Corrected main/Main.hs to use macros instead of Strings;
* Altered function "__" on GUIUtils to call upon getText. It uses unsafePerformIO, so that had to be imported as well.

As of now, this commit breaks leksah. I came to the conclusion that we included "__" calls to some Strings that are being looked for in prefs files and cabal files - which, upon translation, are never to be found, producing an error. This commit, then, serves more of a progress tracking purpose. The next one will probably have the fixes.
Corrected IDE.Session, where there shouldn't be i18n.

Trying to translate preferences were crashing the application. It works now, but there are still some errors.
Adding flags for conditional compilation support.
Adding flags for hgettext conditional compilation support.

* Added 'loc' flag for setting usage of localization;
  * As it's a new feature, default for it is false.

* hgettext probably only works on Linux, so 'loc', even when True,
will only be considered if the OS is Linux.
