Serbian language update and other bugfixes

Castle of no Escape 2

Explore 6 x 6 x 6 = 216 rooms of randomly generated hazards and enemies while collecting the necessary artefacts. Hundreds of monsters are roaming inside, guarding the sword shards — the last known thing to be capable of defeating the demonic castle owner.

Hi everyone, we've recently updated the Serbian locale for Castle of no Escape 2, after a good deal of proofreading from Marko Josifovic and Rados Milicev! Also, after a recent fullscreen patch, language select screen was a bit off, this patch (1.702) fixes this issue as well.
