Translation support about openrhythm

[mdsitton]

Well FoFiX used gettext on windows and osx so i guess it will work? I'll look into this in a bit.

Translations are one of the things i really do want to get correct early on, along with proper unicode text rendering for UIs.

Text should definitely be stored as UTF-8 though that much i've decided :P

Utf-8 is life, yeah ^^ and seeing the awful text rendering issues (cant set fofix in french)... Yeah. Cant even unverstand how FoFiX has this kind of bugs...

Pushed Gettext support in 19f44ad.

Just so you know (if you don't already), all strings should be used like

# File header :
#include <libintl.h>
#define _(STRING) gettext(STRING)

_("the string to be translated")
# Smth like
m_logger->info(_("Loading MIDI"));

The initialization code is :

    /* Setting the i18n environment */
    setlocale (LC_ALL, "");
    bindtextdomain ("openrhythm", LOCALE_DIR);
    textdomain ("openrhythm");

For now (not commited nor pushed) I just pasted this in the main(), but I'll have to find a better place for this. Maybe directly in a preferences/ directory, containing the preferences changes+reading+saving utility code.

Ah yeah, and the bad news is that the POTFILES.in file has to contain the files list. Could not do that in CMake, and that's a shame.
