[Approved] - Up-to-date Finnish translation for MediaPortal

The current Finnish translation of MediaPortal is very bad, and does not give a good impression on the software itself. For example, several missing translations, completely incorrect translations, lots of misspellings, etc.

The current translation irritated me so much that I was forced to revert back to English. Because I wanted to use MediaPortal in Finnish, I had to re-translate it. Although I haven't used much other functions than TV, I am pretty sure that this new translation is much better than the existing one.
