operator macro playback (run operator reports in the console)

operator macro playback (run operator reports in the console)
- reports can be selected with RMB, Border (bkey) and (de)select all.
- delete reports (X key)
- run operators in the console (R key)
- copy reports (Ctrl+C), can be pasted in the text editor an run with alt+p

Details
- Added "selected_editable_objects" and "selected_editable_bases" to screen_context.c, use the scene layers, this was needed for duplicate to run outside the 3D view.
- RNA_property_as_string converted an array of 1 into "(num)" need a comma so python sees it as a tuple - "(num,)"
- add flag to reports, use for seletion atm.

opens a new world of context bugs :)
