fixed bug that was triggered when first creating recent files folder and optimized printing into console

found hopefully a graceful way to deal with situations where gop abstraction/subpatch is open and we select the gop object on parent patch and therefore all its elements inside it (before it would highlight everything inside the subpatch which is confusing to deal with particularly if the edit mode is disabled)

*refined recent documents logic (limiting it to the requested size, added files opened from the command line)
*fixed buggy way of focusing new windows

*refined recent files menu logic to avoid buggy addition of additional breaks as well as provide more verbose info to the user

*code clean-up
*brought the rest of disabled tcl files up-to-date with the 0.45 branch for possible future merge

*enabled drag'n'drop in the main window/console, as well as patches
*implemented properly supported horizontal touchpad scroll (in addition to vertical and shift+vertical, which is being handled as horizontal)
*pd-gui fails to start (missing pd-l2ork in the $lib/bin/ directory)
