port f92dc617867c18216bf4a0e32ece6122b70abc5b from Pd-l2ork: updated bonk~, added bob~, updated makefile to properly build bob~

*updated file locations and made names more consistent across all folders (everything now uses pd-l2ok instead of pdl2ork). Placed user settings into ~/.pd-l2ork/ folder and renamed to simply settings, placed xapian search database for the browser inside the ~/.pd-l2ork folder.

big refactoring #8 : fusion of [hsl] and [vsl] together, and fusion of [hradio] and [vradio] together

remove install-icon rule from install rule, because there's already another icon & desktop file in packages/linux_make/

* disabled warnings about unused parameters (which are pointless) & enabled warnings about other unused local variables (which allow to find dead code)

*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)

*fixed drawsymbol scalars' double names
*improved build process for tkpath
*improved to-front/back logic

ctrl-1, etc, automatically place new object under a selected one and
connect to it
return when editing an object (not a message or comment) deactivates text
