This commit adds internationalization support
We interface with Transifex as our web translation platform.

Two new scripts:
- generate-strings.sh: generates source files in English.
We need one source file by UI file
(Apple's law) + one Localizable.strings for strings in code.

- update-translations.sh: pulls translations completes at 75% at least
from transifex, and cleanup the files (UTF-16LE to UTF-8 encoding,
and remove first line with corrupted char)
