Enable directory structure reorganization

This allows us to move all framework directories from the root of this project to the folder `frameworks/<language>`. It still runs as expected on any framework directories still in 
the project root. 

As an example, I've moved `mojolicious` into `frameworks/perl/mojolicious`. I will move
others, such as moving all the `php` tests into `frameworks/php` once I'm confident I'm 
not causing pain for any open pull requests. The end result of moving everything will 
be a root directory organized more like this: 

* /frameworks
  * perl
      * mojolicious
  * php
  * java
  * c++
* /config
* /results
* /toolset

This should close #448
