make directives global

Hi,

this is feedback I just want to give you. Though I am not an experienced front-end developer I could easily get into the sample code of the application. First I thought, wow there's not much documentation, but if you make the tutorial on "how to create a new page" and look into the samples it's quite easy to figure out how it works.

But here's one thing I'd really love to see. The samples use directives as a part of the specific module. But it would be a lot nicer if they were in a directives package on the same level as the pages package. Then you can just depend on it. For example I did something like this:
`angular.module('BlurAdmin.pages.jobs, ['BlurAdmin.directives.selectpicker']) {`

This way i have a dedicated module namespace for directives and don't make it look like my module has dependencies on other modules, with functionality i don't need.

Sincerely,
Marco
