Changes:

* The hash of textures is now computed the first time they are used. The hash is recomputed if the content might have changed.
* In some games, textures are used as rendering targets (e.g. a mirror or a portal in Portal). The hash calculation of these textures might slow down the game.
-> there is an option to disable the computation of hashes for rendering targets.
* Enable or Disable the support of tpf mods affect now the game immediately.
* Little rearrangements in the GUI.
* uMod can now extract the content of mods to disk and the game loads the textures from there. This solves the huge memory problem of uMod.
