uMod2 Alpha Version:

known bugs: I disabled the remove device function inside the gui, because something in the event handling goes terrible wrong.

Changes:
- hashing algorithm is now a CRC64 value
- changed CRC32 algorithm to a faster one
- in save single texture mode, the selected texture can now be displayed
- the way how uMod get the raw data of the texture was changed
