Subject: General fixes (see description) - closes #17

Somehow the Grub conversion (or anything before/between that) seems
to have caused a *very* weird memory bug involving the heap/stack/sth
overflowing into the video memory which will obviously result in strange
undefined behaviour when data is written to the video memory.

VERY STRANGE. Well, I need to prepare for my finals (Abitur) so I don't know
whether I can fix this issue in the next few days. We'll see...
