This contains just a few version control tweaks beyond v0.9.1, please see release notes for v0.9.1 for list of changes.

This version includes a number of new fixes and features:

Features:

experiments now use create_node and create_network methods instead of node and network properties
participants are now assigned an end_time when they finish the experiment
Wallace no longer sends emails when a database error is noticed
Fixes

Clock code now access the participant table and not the psiturk table
Notifications route now properly commits changes to the participant table. This fixes an issue where participants failing an attention check would trigger a recruit/bonus payment loop.
The assign properties function no longer overwrites existing values if nothing is specified.
