numerous fixes and improvements to abstractions and help files including reworked image drawing logic, improved metronome preset ordering and updated presets throughout the demo and help files, improved icons, clean-up and optimization, beter enveloping, and more.

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).

fixed a number of small bugs including a segfault, inability to open local files, adapted code to reflect improved path searching, made image draw gray square when no image is available, reworked the way image allows for spilling beyond the GOP area by adding a second float flag, updated help file to reflect new features

fixed incorrect coloring of inlets after an unsuccessful connection (e.g. signal to a non-signal inlet)

Fixed bug reported by Andras Muranyi where clearing a preset would erroneously delete two adjacent presets. Added "sort n" command that allows linear sorting starting with number n (default 0). Improved output from preset_hub_store (via hub's outlet) to report failed creation of presets with negative numbers (successful creation of preset n would output "store n 1," while failed one would output "store n 0").

improved preset hub/node mechanism to allow float names, as well as $n argument names, thus allowing for more modular designs. Fixed bug where node locations were incorrectly identified in embedded subpatches/abstractions.

added experimental optimization for binding abstractions as per following post on the pd-list: http://lists.puredata.info/pipermail/pd-list/2013-08/103688.html

fixed 2 segfaults: one when trying to delete array that is being read/written to by a dsp process (e.g. tabwrite), and another where creating undo checkpoint when deleting array would generate bogus data that would crash pd-l2ork. Currently undoing array deletion is not supported by undo.

experimental implementation of disabling drawing outside the GOP array boundaries (currently disabled)

fixed regression due to idiotic way how arrays and scalars are allowed to spill outside its GOP frame...

fixed bug where curve parameter was ignored when entering value pairs (target duration) without the curve parameter

refined multiconnect's 3rd option and code comments for 2nd and 3rd option to reflect use with only 2 objects selected
