* using fancybox as JS lib for displaying photos

related to federation@5c90e6d6
fixes #35

* Refactor JS
* Refactor CSS
* Remove RevealJS
* Add Pagination to stream views
* Remove all git tracked vendor libs

All future vendor libs will be installed via npm:

    npm install --save <new-dependency>

Then add the new acquired library to the `.include_vendor` file:

    [...]
    # My New Lib
    js:node_modules/new/dependency.min.js
    [...]

You'll find more examples in the file itself!
