Renamed VagrantFile to Vagrantfile
Better DSN string building (fixes a few bugs)
Removed dbDriver::exec() (use dbDriver::query() instead)
Bug fix - Allow an object to be passed into the dbDriver class (like a PDO object)
Bug fix - Allow an array, string , or PDO to be used in $params
Better error handling for dbDriver constructor
Testing fix - Don't rely only on PDO to tell us if we're in a transaction (which will fail when PDO is a mock)
Added read-only mode to debug info
Use built-in isReadOnly() to determine if we're in read-only mode
Test suite for dbDriver_mysql
