- added optional grid distance labeling
 * adds distance markers every grid unit (not sub grid unit)
 * a few small changes and cleanup in visual editor and helpers
fixed helper's labeling on-screen size issue : added displaySize param to the drawText method for more flexibility
another hackish attempt at solving the code editor (codeMirror) resize issues: now it really seems to work, withouth weird scrollbar stutter
issue
- added contributors to readme (thanks guys :)
 * added back openjscad info
- added in-app log support ( closes #76)
 * very basic but :
 * has log levels
 * works from web worker (background processing) too
 * is displayed inside the console VIEW , not the browser's console

-cleanup and restructuring of compiler:
 * better organized
 * more correct use of jquery deferred's pipe
 * remove some clutter
 * added log handling (see above)
- added project auto reload support
 * modified the browser & dropbox stores to support it
 * current/last project name and storage type is stored in localstorage (independantly of the browserStore of course)
