*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)

implemented autorepeat filtering for Unix-based systems so that key, keyup, and keyname only report non-autorepeat events

differentiated key, keyup, and keyname's help files so that they all call their own individual help files (rather than convering onto key-help.pd)

tkpath version bump (and currently a new fork until this gets merged upstream) fixing scaling bug where applying scale matrix (or scaling) objects would leave artifacts since its bbox translation did not take into account transformation matrix

added helpbrowser to the same class so that Unity properly groups it with the rest of pd-l2ork windows

Removed unnecessary debugging hooks. Added -unique flag that enables spawning of multiple instances of pd-l2ork (disabled by default which means all new file opens will be forwarded to the existing instace). Made ALSA default driver

*gop leaving stale vanila objects
*fixed bug where closing subpatcher of gop patch/abstraction redundantly opens gop patcher/abstraction
*fixed bug where reordering did not properly deselect previously arranged elements

forgot to add another change to make it in sync with 0.43+ branch where real-time is default behavior.

Allow inst_dir variable of tar_em_up.sh to be overridden.
