Changed out how messages are sent/received.

No more length leader on the messages. Also, received messages have
their signatures verified and all outbound messages are signed.
Tweaked the client for the signature stuff.
Returned message must be ascii.
Merge branch 'socket_message_work' of github.com:FellowRoboticists/telep into socket_message_work
Cleaned up some commented-out code.

Should have cleaned this stuff out earlier.
Added signature_handlers to the application file.
Added system startup for ws_server.

This took care of the startup stuff. The init script and
the configuration.
Modified the location of cert/key.

The new location should be the final location.
Created script to generate robot keys.

Just a bit of macro function to generate keys that have common
attributes and a consistent naming convention.
Created the make file for deployments.
Ignoring keys/certs.
Added target to deploy telep
Mods to deploy telep in standard location.
Deployed keys and configuration for keys.
Added handling for closed sockets.

The trick here was figuring out when the socket got closed.
