Dan 5f6a61c93f * SpiffWorkflow event_definitions wanted to return a message event's correlation properties mested within correlation keys. But messages are directly related to properties, not to keys - and it forced a number of conversions that made for tricky code. So Messages now contain a dictionary of correlation properties only.
* SpiffWorkflow did not serialize correlations - so they were lost between save and retrieve.

* When comparing Correlation Property values - we are storing these values as strings in the database and can't convert them back to integers later, so I'm changing everying everywhere to compare after conversion to a string.  Don't feel great about this one.
* By using an SQL Alchemy join table, there is a lot of db queries we don't need to write.
* A few handy fucntions on db models to make it easier to work with correlations.
* Updated tests because I changed some of the BPMN models we were testing against.
* Database migration to use the new constraint names with the alternate form of the join table between correlation mesages to instance messages.
