Visual update, and compatibility improvements

Hey, this PR, addresses a couple of things:

* f589c20c74d741c4ab26e4ad4e8e27592009d3a1 Switch short tags to standard PHP tags
    * Short tags are OK, but as this is a module, it should be easily pluggable and enabling short open tags in php.ini kind of breaks that.
* af050871d6d1aff2c2c8abff0d1c622d5ffd5ad1 Replace classname bakslashes in URL route params
    * Forward Slashes and Back Slashes may break a route in certain server configurations, returning a 404 eror, **AllowEncodedSlashes** may be required to set to **On** on Apache to allow them, but this is a server configuration and Zf2EntityAudit shouldn't force that.
* 4f4b81e123472d8026cfc078ebb78ad37b459368 Bootstrap 3
    * Views scripts has been updated to display correct Bootstrap 3 classes
* 4c91966115271e9c09ceec26a113f6331a156d35 Visual adjustments
    * User View Helper has been touched to implement Bootstrap 3.

Comments will be appreciated.
