Scripting changes. Add override of mapgen, templatefilter. Expose waterline, add "GetAmmoCount". Default to amNothing in uAmmos if entry is not found.

add for mine strike too. as cheezemonkey points out, mine bounce is height dependent.

Set more generous minimums. Flicker seems to have nothing to do with minimum size. I get it even for fairly large dimensions after scaling down from a much larger size. Similar to issues with zoom from about a month ago, before unc0rr fixed them.

restore screwed up test

don't override user defined size when resizing

Check if we need to download and prevent user from reaching the startgame menu because it needs images from the download

enable window resizing (tested only on linux) - fix issue #103
