* All alpha settings now devolve onto the color strategies, and almost all of the color
  strategies now support functioning with and without alpha.
* Removed the old channel & mask stubs that were never associated with any meaningful
  implementation. More API cleanups in KisImage.
* Integrated new new image dialog with some new settings (but I still need to add
  those to the loading/saving in kisdoc)
