Code "reload" for development mode

[clemesha]

Having all code reload on refresh is extremely useful for quicker development cycles. With a combination of a settings flag, like "DEBUG", plus using one or more on the below functions, we can achieve this.

Python has the "reload" built-in function.

For Twisted, there is "rebuild" here:

There are some interesting ideas here:

Which basically boil down to doing a kill of the process, then restart.

I tried to get the code sketch at http://twistedmatrix.com/trac/ticket/4072 working but didn't get very far. Big help, I know.
