Start work on stoneridge master process
Use constants for queue names
Handle default needs to take kwargs
Rename all scripts to match new world
Make cronjob use new names
Start working on cloner

This still doesn't handle try builds at all (though it pretends to, by
accepting the args from the master). The source directory creation needs
to be changed for that to work.
First attempt at making cloner handle try builds
Update gitignore for local testing directory
Have example config usable for local testing
Make logging work in cloner
Lots of fixes

*stoneridge.logdir is no longer needed
*Makes the cloner work
*Makes the master run cloner correctly (I think)
Add license to srmaster
Make queue an __init__ arg for QueueListener, not a class variable
First whack at a scheduler
Add worker process to replace cron job
Remove cronjob and wrapper
Add new config entry to example config
Forgot to clear this out
Cloner is no longer a cron job
Make queue config variables "hidden"

They're prefixed with _ so they don't pollute the general namespace that
is usable by subclasses. This also changes self.setup to take arguments,
namely those arguments sent to __init__ that aren't handled directly by
__init__. This is instead of using self.args (which has been renamed
self._args, and should stay hidden in the parent class unless absolutely
necessary).
