*backported vanilla patch http://sourceforge.net/p/pure-data/pure-data/ci/f535c339c99a74edb3920c2e630500df128b7d8f/

*Ported open_via_helppath from pd to fix inability to open help files when starting pd-l2ork from the doc/5.reference folder.

fixed regression where empty image box appeared on gop-ed parent in incorrect locations and/or it was not supposed to show up at all. Some refinements to the path detection/removal of debug output.

revamped path to support ~/, root paths, relative paths, as well as special tags like @pd_extra that expands to the location of the extra folder (other tags may be added later if necessary).

streamlined @pd_extra parsing for easier integration with other file open calls including externals. Added it to open_via_path

fixed noselect bug when line is selected and one clicks on a blank canvas which should also deselect selected line. also made pd_extrapath struct global as part of s_stuff.h so that ggee/image can use dynamic descriptors for retrieving of files (.e.g @pd_extra is translated to the pd's system-wide location of the extra/ folder)
