updated Readme to RABDF-specifics
Wrote own tile-based grid system with support for half and quarter tiles. TODO: figure out how to find out if a tile is last on the row or not
implemented custom grid system in Sass, and custom gridify script to be run on mixitup. Lovely blocky flowy work, and the opportunity to use the height-summation to dynamically insert elements if ones are missing/extend existing elements to cover up gaps. TODO: fix the filters in accordance with the new grid system.
