[PATCH] testbot/Janitor: Notify the administrator whenever an error occurs.

[Francois Gouget]

Errors are also recorded in the general TestBot log but administrators 
would normally only read the log when something breaks the TestBot so 
that they would miss messages about unexpected TestAgentd.exe files for 
instance. Directly notifying the administrators about such issues makes 
it more likely that the Janitor script will remain up to date.
