minor improvements
More cool stuff
More good stuff
Super-cool dependency graph
fixed problem
Misc stuff
Added "safe" unpickling

eg. for deserializing exceptions / return values, when we do not want bad data to cause the view to fail
[#13] Now using "bytea" type for pickled fields
Storage fixtures now have scope='function', in order to achieve better isolation
Hopefully fixed problems with null bytes in pickled fields (use BYTEA + buffer())
Better test for builds
Added functions to load/dump YAML-based job configuration
Improvements to job execution context object
Removed zombie lines
Added pyyaml dependency
New interface for the job state storage
Partial implementation of the new postgresql-based storage
New object to hold / manipulate (nested) build progress reports
