presets for operators, re-using same preset system as render, cloth etc use.

- operators need to enable the option OPTYPE_PRESET or 'PRESET' in python.
- hidden properties are not written.
- currently this only works in the file selector (enabled for FBX/OBJ export)
- currently the menu label doesnt change when presets are selected, this is a TODO, not so simple since the UI is defined in C and the label in python.
- presets save in "scripts/presets/operators/*id*/*.py"
