empty/untransated locales in Tor Launcher
While working on #11699 (moved), brade and I noticed that some Tor Launcher translations only have a few translated strings. For the DTD files, most of the strings are "" or they contain the English text; within the properties files everything is commented out.
There appears to be a perfectly good Polish translation under pl (instead of pl_PL). On Transifex, I only see one Polish translation (pl), probably the good one.
Locales that seem to have this problem: ca-ES, ca@valencia, ms, pl-PL, sv-SE, zh-CN.GB2312, zh
Should these locales just be removed from translation.git and tor-launcher.git? Where did they come from?
