Fixed bug introduced in previous commit that caused everything to break
when persistence.sync.js was enabled.
NPM version bump to 0.2.3
Fixed a bug that fixed a bug of an older version of the mysql driver.
Update node-mysql to 0.7.0 (npm install mysql).
Code indentation, version bump
Set-up library to be used a node library installable via npm. In fact,
it's published on npm right now.
Put back the IF NOT EXISTS in the INDEX generation. This will break the
MySQL back-end, but I'll have to find another solution for that.
Added link to the persistence.js GWT wrapper.
