Modularization Release

To better facilitate future development and maintenance a major re-work of the project structure has been done.

Filters are now stored within the filters sub-directory
Filters are now auto-loaded. Future plans are to add a section in configuration to enable filters

All existing configurations should still work with this release.

Please note:

If you were using Readability.php you will need to run composer install inside the filters/fi_mod_readability` folder
