13.1 scripting addtions

Some small but handy additions to the scripting capability of Capture One 20 (13.1.0):

position - (property for variant clones - equivalent to UI position)
available styles - (of application - list of the available/installed styles (by name)
compare mode - (set the before/after mode and if it is enabled)

Bug fixes to the following:

Fixed an issue making next capture keywords (Enterprise only)
Fixed an issue with "export crop method" incorrectly identified as integer
Fixed an issue where sometimes "current document" would not work immediately after making a document
Fixed an issue where "delete recipe" would do nothing if the recipes were hidden.
