A few last minute fixes for 0.8.2 - see the description for details

[eugmandel]

1. Fix: the link to the action list validation operator reference page was out of date
2. Fix in the config version detection logic - check for either validations_store or validations_stores top level keys in the config to determine if this is a 0.7.x
3. Fix: temporary table names that start with a digit are not allowed (at least in MySQL) - added a ge_tmp_ prefix
4. Fix: double quotes around the temp table name were failing the execution on MySQL. I could not find a SQLAlchemy way to create a temporary table, so implemented a conditional logic based on the dialect name - not great, but this fixes the issue
5. Added a couple of details to the docs section on migrating to 0.8.x. Instead of meticulously documenting all the steps of migrating the config file, I put a call to action to get help on Slack
