Chromeless window and resizing

[ramezrafla]

We are interested in using this plugin but need to be able to set the (x,y,w,h) of the modal webview. As well, we want to have the option to hide the toolbar.

I am checking in before we do the work at our end (we will be hiring a freelancer). Would you accept PR's to this repo to update it?

PS: Does the loadstop event fire properly now at end of page load (i.e. not ajax)? Thanks
