TalkBox v0.5

Many new improvements:

• async event handling via asyncore and callbacks
• new soundsets contributed by Christine and Max Feraday

TalkBox v0.4

• Added mouse as a controller using evdev.

TalkBox v0.3

• Added support for multiple user-supplied soundsets (defined by a directory with specific json file)
• Added volume controls.

TalkBox v0.2

• Fixed bug where pins 8-11 were inaccessible due to reading of only one byte instead of a word.
• Added script that should be added to /etc/init.d to make TalkBox a linux daemon (start on boot) based on instructions found here: http://blog.scphillips.com/2013/07/getting-a-python-script-to-run-in-the-background-as-a-service-on-boot/
• Changed sound files to numbers, made them absolute paths in the code as a quick dirty hack for daemon.
