Metadata: ALL -- Minor cleanup, standardizations, remove unused variables. Removed namespace (was incorrect anyways)
Metadata: XBMC -- Strip leading/trailing spaces off Actor's names.
Metadata: TIVO -- Override 'non supported' functions to prevent erroneous metadata from being created.
Per Tivo docs, the value for rating can only be a whole number or a half..  example: 1, 1.5, 2, 2.5, 3, 3.5, 4. We use 0 to 4 and also return a float with the precision of 1 place.. (1.0).. waiting to hear back if this is really not allowed.
Metadata: MB -- Re-order and cleaned up the .xml generation to match what MB3 is generating. Note that for mult-ep it looks like they aggregate the episodes into the first ep.
