Fixes for router url changes & erlydtl update

Hi Evan,

This pull request fixes a few problems with the latests url tag perf improvements.

* Writing {% url without action
* Typo calling to mochiweb_util:unqoute/1

This commit fixes the admin console that was broken with cb master.

Also, updates erlydtl dep to get the new error reporting on vars (wow):
```
{undefined_variable,[{name,xx},
                     {file,"src/view/layouts/tabbed.html"},
                     {line,{26,13}}]}
```

I will be performing a fully test of the actual cb code.

Thanks
