MacCsound 1.1 for OSX!

Changes & Bugs Fixed
• MIDI Out Implemented.
• New [optional] Memory Manager. if you specify a number > 0 in the options view, the csound render will pre-allocate that amount [in megs] of memory to use for processing. it probably will have no noticeable difference, but using the memory manager will eliminate any memory leaks in CsoundLib, and may increase speed or eliminate some real-time-related crashes.
• New render option: Write to file during real-time performance. [currently only stereo AIFF supported]
• Added Victor Lazzarini's new pvs opcodes.
• Fixed crashes after stopping render.
• Fixed bugs when audio device presents itself as 2 [1 in, 1 out].

• Made temp files write to /tmp instead of SFDIR.

• Application bundle now contains CsoundLib.
• Every user now has $HOME/Library/Application Support/MacCsound created automatically for default.csd and Effects
• Revised some preference formatting that might have caused problems for some.
