FLP 1.042 released

Some small new features:
There is a countLanguages and countStrings function in the ChooseLanguage class now.
And i've implemented the possibility to use alias languages. Let's say you have a language directory "en" with translation files in it and now you want another language directory "en_uk". Instead of translating everything again or copying the translation files from one directory to the other all the time you just place a file called "redirect" into the "en_uk" dir which contains the name of the original language folder (in this case "en").
