Project name query parser

[gsingers]

It would be nice to do like JIRA does and detect when a user just wants to search within a particular project by adding query parsing to support this.

For instance "fusion html transform stage" would select "fusion" as a project filter and then execute the rest of the query with that filter applied.

I think this can be a fairly straightforward implementation:

1. Detect the keyword at the beginning or end of the query
2. Setup taxonomy/stored parameters (or rules once we merge #52) that inject filter queries (and other params if desired) for that category.
