2014-05-12 Release

• Important: changes the syntax of deploying to Tessel. In order to deploy to RAM and view output from Tessel, use tessel run [script]. In order to deploy to Flash and have the same program run when you reset the board, use tessel push [script]. If you would like to remove the code from Flash, run tessel erase.
• Fixes a bug where output was closed even when GPIO Interrupts were pending.
