Change how current projects page work

[Patrik-Br]

Currently it works as blogposts. Would be better to have one page with all the projects where we would be adding/removing projects from.

I got working demo looking like this:

Projects are given category TM/MR/MS, card is automatically adjusted length based on the length of text, all cards in the row are resized according the longest card.
Data are feeded from .yml file which can be accessed only directly from GitHub. It is not ideal, currently working on feeding it over the admin system instead.
