What's new for 2.3

@rwhitley This is basically the same notes as @bhariharan 's.
There are some changes they need in their html (it's in the pdf already) e.g.
Instead of doing cordova.require("salesforce/plugin/oauth"), they should do cordova.require("com.salesforce.plugin.oauth")
They need to <script src="cordova.js" /> instead of <script src="cordova-xxx.js" />
They need to remove <script src="cordova.force.js" />, cordova.require will inject a <script src="..." /> in the page at runtime when required
