Smoke:

* Enable cache for high res + new preview
* Bugfix for smoke banding (in cooperation with N_T)

Hint: Work-in-progress regarding collision objects so can be broken, didn't test

Hint2: jahka enabled a general particle panel but 
* bake button doesn't work
* step is not supported for cloth
* several other things there ;)
