We use 'defaults export' rather than 'defaults read' to grab the prefs data on OSX now, which loads the prefs much faster and also properly deals with filenames containing UTF-8 characters.

Otherwise search paths from old program versions installed in different places may keep piling up, eventually causing issues when submitting prefs data because of buffer limits.

Turn the user config dir (~/.pd-l2ork on Linux) into a #define so that it's easier to patch it up when needed.

Add support for loading and storing the MIDI API preference (commit 516eba76 from vanilla by aib <aibok42@gmail.com>, slightly edited.

Keep track of the number of audio and MIDI device entries in the preferences, to avoid zombie entries on Mac and Windows. Proposed fix for #213, needs testing on Mac and Windows.

Keep the ALSA sequencer port information used by the GUI in sync with the actual device configuration. Fixes #203.

This change allows curly braces {} to be accepted as keypress events and entered into object and message boxes. It doesn't change the quoting rules for these characters, so [print] still escapes them with backslashes.

Port pd-l2ork upstream commits from Dec 7, 2015 improving the handling of $ substitutions in GUI elements. Also fixes #195.

cleanup iemgui dialog form names, replacing dashes with underscores. Fix stray bugs in canvas dialog, and clean up css selector names

for reading preferences on Windows, try HKCU first, then fall back to HKLM. For writing, only write to HKCU

stop using "x" for sending iemgui colors-- while it has a precision formatter, it doesn't have a maximum size formatter (and it can't because 64-bit archs need the larger values)

cherry-pick Albert Gräf's branch: Comment out a bunch of debugging statements which add a lot of noise to the console.
