Bug 536282 - Check whether processing step is available
Extend ProcessingStep with isEnabled() method that checks if step's
dependencies are available. ProcessingStepHandler's canProcess will
ensure that all required processing steps are enabled and skip this
check for optional processing steps.
MirrorRequest's perform(IArtifactRepository, IProgressMonitor) method
will skip optimized artifact if it can't be processed and chose
canonical one.
Pack200ProcessorStep's isEnabled() checks if 'unpack200' CLI utility
is available by calling UnpackStep's canUnpack().
