Hungarian translation and minor grammtic error correction in the English version

The Hungarian properties file is UTF-8, I don't know if that works. I compiled the project but yet to have to get a GlassFish for it. Please try it if you can, because it can happen that some texts are longer/shorter and it may mess up the layout. If the UTF-8 doesn't come out well I will encode it to other representation. Unfortunately there are tons of Hungarian accents, and some of them are tricky, like "í" (long single i) "ő" (long double o) or "ű" (long double u).
