I don't know how this managed to stay, since I removed it in a prior pull request.

Last minute optimizations.

Remove circuitpusher's circuits file.

Removed commits.log.

OF1.3 branch bug fixes and unit tests

Added support for features request message via the REST API. Changed the case of some JSON keys to camel.

Updated circuitpusher with new SFP syntax. Updated Forwarding(Base) to use a default priority of 1, since in OF1.3 we have a priority=0 table-miss flow that will also match. Trying to update the Web UI to display flows correctly.

Added insertion of default table-miss flow for OF1.3 switches. Also added clearing of switch tables when switch connects. Both of these only occur if the controller is in the MASTER role for the switch. It if is placed in SLAVE, the switch flow tables will not be modified. Also had to update the unit tests with new expectations for IOFSwitchBackend fuction calls (which was a real pain).

Added REST API support for getting list of loaded and all modules. Tinkered with Web UI's flow action display. The problem is that the actions (write and apply) will not display for any flow. Need to spend some time figuring out the issue.
