Due to changes with Mopa and TWBS this hack has been added: https://github.com/phiamo/MopaBootstrapBundle/blob/master/Resources/doc/assetic-configuration.md

To allow Assetic to run correctly with cssrewrite the glyphicons are included from bootstrap.
The bootstrap file has been added to setup to current file locations with bootstrap.
Layout has been updated to include new bootstrap reference file.
