Remove the --previous option of po generation. It broke some translations.
Remove the translation of PCSX2 version, no point to translate C format symbol.
* add a PERL script to ensure translation quality (ie check c-string format)
* Fix c-format error as best as can! It will hopefully fix various potential crash
