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.

More fixes for compatibility with Arch Linux.

Fixes for compatibility with Arch Linux.

fixed inconsistent scrolling amount when using various scrolling methods as well as scrollbar detection logic

clean-up plus an ugly hack for autopatching to trigger getscroll (for some reason tkpath either draws out-of-order and therefore does not execute getscroll when asked or there is something else amiss that is yet to be determined). For the time being we force getscroll 100ms after autopatch.

*the cursor should change to a click arrow when hovering over a scrollbar. Various improvements to scrollbar logic.

improved keyboard interaction with arrays (shift+click adds a point, ctrl+click deletes it--still need to figure out the role of shift when wonset is set) and instantaneous cursor update. minor refinements to drawsymbol.

*better getrect for scalars inside plot/array (entire points are now selectable instead of arbitrary rectangle around the object)
