login button and text selection problems

[jhaigh1143]

I discovered a Unity specific issue with this implementation. The Shift works as a modifier for keys getting to upper case etc, but does not register on it's own as a Keypress / Keyrelease (i'm using unity 5.0.1f1 & the newest awesomium w/ this plugin).

Solved by adding an input hook on update that registers it's own versions of injected keypress/release for AwesomiumUnityVirtualKey.LSHIFT;

Thanks for your great work on this wrapper!
