ENH: Teach set/get_property about CACHE properties

Browse Source 
This adds the CACHE option to set_property and get_property commands.
This allows full control over cache entry information, so advanced users
can tweak their project cache as desired.  The set_property command
allows only pre-defined CACHE properties to be set since others would
not persist anyway.
