Update Forge Embedded Runtime to 1.2.2.Final

The embedded forge should be updated to make sure that the html5 scaffolding works well with it.

The ticket monster tutorial was checked to work fine with Forge 1.2.1.
As for the ticket monster demo part, it needs a little fix in the admin_layer.fsh file. But running this file seems to fail also with Forge 1.1.2.
