Generate unique identifier for blockly at startup (stored in /etc/blocklyId)
abstracted out the upload script so that i can call it from other functions
The btu now responds to server packets. I have not yet tested the calls to blockly_webserver although.
The rails server can now push code to the BTUs successfully.
The guids now come with a Luhn checksum.
Fixed bug in guid algorithm
Use A-Z (excluding O's) when generating GUIDs
Use the blockly uuid as the source for packets sent to dax.
The code url from the server now just returns the codetext instead of json.
Don't recompile code when it is sent twice in a row.
Remove the auto-generated code files that change all of the time.
Make sure that the generated guids are of the same length (14)
Use dax instead of my local ip
Rename /etc/blocklyId to /etc/BlockyTalkyID.
Merge pull request #3 from ealter/master

Deeper integration between BTU and rails server based on Eliot's senior project work.
