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.

had to revise pdlibbuilder script to get it to build on OSX. Can't really push it upstream as it's just a hack (and upstream has been aware of the problem for some time...)

handle the discrepancy between submodule name "lyonpotpourri" and libdir name "lyon" more gracefully

get rid of erroneous lyon/lyonpotpourri folder so as to start completely over with the lyonpotpourri submodule

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)

shorten lyonpotpourri to lyon in Makefile to match the new submodule name (which itself was changed to match Pd-l2ork)
