"operator.ED_VIEW3D_OT_viewhome(center=1)" calls the operator, converting keyword args to properties.
Need a way to run scripts in the UI for useful testing.
Still need to deal with operator exceptions and verifying args against operator options.
Added temporary WM_operatortype_first() to allow python to return a list if available operators, can replace this with something better later (operator iterator?)
