Revel should be one directory

[msmith-techempower]

Currently, there are three directories (revel, revel-jet, and revel-qbs), but these should be one dir with separate test/code as necessary.

My understanding is that revel (the framework) is the same for both, but jet is used as the ORM for revel-jet whereas standard database stuff is done in Golang for revel. The same is true for qbs
