* add flag for compatibility with older OSX versions
* change library paths in script so that external dependencies are found
* build with jack support

fix regression where glist_select can send messages to the GUI before the window or its elements actually exist. (Same thing happens in Vanilla, but tcl/tk silently ignores tk canvas itemconfigure messages for non-existent objects)

fix #114: can't copy-paste ASCII character 160, non-breaking space. Now we only remove consecutive \u0020, and leave the non-breaking spaces alone

fix #119: store canvas title for later use. This will properly display the title for a dirty canvas in the case where the Pd patch is mutated with a loadbang (and properly other cases, too)

fix a crasher with gtemplate_new dereferencing a freed pointer, and harden rule for creating a struct

Remove kludge for menu popup position. As of nw.js v.0.16.1, it appears that the popup menu behaves correctly with zooming and scaling

These happen in Pd-Vanilla and Pd-l2ork, too. They happen when an iemgui is inside
a gop window and outside of the gop rectangle area-- Pd still forwards gui
messages for them.

use individual help patches for higher math objects ([cos], [sin], etc.) and cross-reference with math-help.pd

first draft of saving the preferences, including the gui preset (still won't write to file for some reason)

These bugs were discovered via static code-analysis

(The CID numbers are the "Coverity IDs" used to identify the various bugs)

- Don't free binbuf within glist_readfrombinbuf (CID:74871)
- it must be deleted by the caller
- Initialize sockaddr_in (CID:74861,74862,74863,74866)
- Initialize indelay/outdelay (CID:74864,74865)
- Initialize device-arrays (CID:74853,74854,74855,74856)
- Closing unneeded sockets (CID:74827)
- Initialize sockaddr_in (CID:74860}
- Close file-descriptor if the soundfile is unparsable (CID:74822,74823)
- Close file-handle in cleanup (CID:74816)
- Call va_end() when handling variadic args (CID:74872)
- Added missing break (CID:74800)
- Prevent NULL-dereferences (CID:74792,74793)
- Size checks when copying into string buffers (CID:74844,74845,74846,74847,74849)
- Freeing no-more used storage (CID:74832)
- Fixed code block (CID:74806)
- Initialize sockaddr_in (CID:74860)
- Initialize array-values to 0 (CID:74867)
- Free allocated memory (CID:74813,74830)
- Removed allocation of unused memory
- Use pd_free() to free templates (CID:74814)
- template_free() does not free the entire structure (it misses the pd_new() part)
- initialize variable (CID:77865)
- Prevent NULL-pointer dererencing (CID:77864)
- Free heap-allocate binbuf after use (CID:74833)

we just hide the "apply" button

fixed up dialog, backported some code from Pd-Vanilla 0.46
