Demo Day 50 Update (Late record)

For this DD50 I tried to make a Linux build, which turned out to be harder than I expected. No Windows version is provided this time. This should work at least on Ubuntu LTS but you will need to install the dependencies yourself (SDL, Freeimage, maybe more). As the bug in the UI was fixed, the combat was included but other than that no new content has been added from the previous (DD44) version.

Later I should try to make a version with dependencies included so that it can be played without additional hassle.
