fixes issue #27
added a  partio attr on the particle shape itself  that defines  which entries have been checkboxed,  it works "live"  so as many changes that are made happen on each check/uncheck.
Also added  better directory handling  and defaults for  unknown directory stuff.
added support for changing the directory path manually  by editing the text field.
fixing  issue #24
added support for  "byFrame"  attribute  to  skipframe playback  particle caches
setting  disney  partio for houdini  stuff to not build.
partview overhaul
-fixed crashing with rapid key press repeats and color channels.
-lowered  CPU usage by  removing constant  timer loop
  now it only updates and runs the timer loops when interaction is happening, either keypress or mouse movement
-removed  'a' and 'c'  keypress events
-replaced them with  colorFrom and alphaFrom right click menus that read the whole list of PP attrs so color and alpha are now user selectable
only thing that is still not quite working is the brightness controls and sometimes there will be double frame jumps forward or back.
Merge branch 'redpawfx' into partio4Maya
forking  this problem to work on possible solutions.
fixed  the mem leaks in the partviewer, reset function seems to actually work correctly...  I missed another leak that I was not accounting for.
Merge branch 'frameMemLeak' into partio4Maya
this adds the  partio base code for  a "Reset" command  to  the partio lib
which hopefully will be able to  fix the mem leak in the maya plugins now  as well
fixed  partio4Maya  visualizer and  instancer  memory leak,  would still like to  implement this better in the  partio core.
Merge branch 'partio4Maya'  into redpawfx
Merge branch 'partio4Houdini'  into redpawfx
partio4Houdini  is  thanks to  Milo-Green and his fork/branch  I added  cmake project love to  tie the whole thing together.
updated  partio4Maya version to 0.9.6
added missing  findHoudini.cmake  file
added  getCXXCompiler cmake file
switch for windows compile include issues
glut couldn't be found on windows in cmake config
reverting,  there's somethign else wrong with finding glut on  windows...
udpating cmake stuff  to compile in windows.. we'll be bouncing back and forth like this for  a little bit between platforms, making sure one cmake setup works for everything
Removed build of  ICECACHE for now (need to remove from  maya plugin as well)  since it needs work to be cross plat compatible
Haven't finished  updating all the cmake stuff yet for windows .. need to do  maya plugin and eventually add support for arnold and houdini plugs
updated cmake to separate build from output/install dirs for libs and  bin outputs... cmake was getting confused
updated  contrib top level to switch around  win32 and apple to build contrib stuff until later.
