UFO:Alien Invasion Code

* removed exif headers from jpgs

* use the trunk base content

* delete the base to allow to copy the trunk one

* fixed all of my known textures that won't work with GTKradient.

* resaved all the files i uploaded yesterday due to a file format issue.

* converted jpeg from exif standard to jfif standard (they were not loadable in-game)
* TODO: maybe some of the other new jpeg textures are affected, too - then please resave them with e.g. gimp

* replacing un-GPL asian textures and adding 1.
