Fix for #31 Make it easier to do clean builds.

Now offers command line arguments "-clean" and "-noclean" to force selected buildprocesses to run with either setting. Added an option to the UBSAssetInspector to select if the buildprocess in it should be run with CleanBuildCache option on. This can be set individually in the build options of each process.
