Log panel for arbitrary raw log messages

This change does the following:
1.  Break the circular reference between CTL and the webservice
2.  Establishes the log panel at the bottom of the screen
so that raw log messages can be show.
3.  Transfers the CTL logs to the UI by overwriting the CTL
logger.  This requires a new CTL client each transaction
4.  Adds in net/http specific logging for the backend
