0.2.0 goals sorta

[Halatnikov]

high priority:

• clean up all the code after 0.1.0 and fix bugs in the process

• hopefully also fix gameplay bugs (i might need help on this)

• add a few more essential objects and special objects

lower priority:

• skin system (make it work in multiplayer too)

• better menus (at least main menu and level/skin select for now)

• beta update branch

• some kind of "installer" if no resource files are present

even lower priority (might delay):

• level finish

• music player

• logging

• bring back language translation

• settings and saving of them (at least just an .ini file without a menu)
