enable window resizing (tested only on linux) - fix
issue #103
this should fix the double free that happens when closing the sdl window on ios (untested)
FREE AT LAST!!! SDL came around a (mostly) sane way for implementing rotation events, so we can scrap all the workaround code that has been added to workaround it!! Also this allows us to use proper (internal) multitasking handling and can simplify optional settings and other yet unexplored features. Yay!
Fixed AddFileLog, there's now a log created in /sdcard/Android/data/org.hedgewars.mobile/cache/Data/
