Adding sass partials from motherplate project

The motherplate project (https://github.com/leemunroe/motherplate) helps
in removing the sassybuttons and susy grid layouts. Moreover all the
functionality is placed in the partials scss; moreover, the normalization
is not that radical like the ben frain normalization; which however is
still existing in the partials folder and still included into the core
Adding footer to the complete layout.

However, the colors etc. must be moved to the variabes.scss.
Moreover, the template changed a little to simplify the css selectors.
Finished footer aligment for desktop variant view

Merged also the config variables into _variables.scss, which defined
the main and hover colours. Added also mixin (thanks to the internet)
which helps in creating triangles easily. This helped in creating the
current footer. The text is just fixed absolutly at the bottom, which
does not work in tablet or mobil viewport sizes.
