Lots of changes; the GCond stuff is kind of neat
Space was being allocated and deallocated for values as if they were guints instead of doubles.
The code will inspect the environment variable SCRIBL_LOG and not output log DEBUG and INFO messages unless the log level is high enough. The log levels are the same as the ones used by gstreamer (e.g. 5 == log everything, 4 == log INFO but not DEBUG, etc.). Settings SCRIBL_LOG to an integer less than 4 does nothing right now (should be fixed later).
This adds support for actually serializing counters to disk. It also introduces a change whereby counters are now named.
This contains lots of fixes from the hacking branch, including * exiting scribl works again * values are all doubles (instead of guints)
