Restoring original geometry after size normalisation (#126)

* Use arcs to save space on path arcs and be more true to original geometry

* Use single path for equal width rectangles

* Deleted unneeded commas

* reduce path count by using stroke linecap

* use single path instead of 4 rects, use fill rule to forego entering M for every rect

* Using arcs

* Fix typos

* Changed side for OSI icon

* Changed size for windows logo

* Changed size for ghost logo

* Shrunk digidentity to two paths. Some times an arc is cheaper on bytes than a circle element

* Concatenated paths

* RSS icon shrunk to a single path of 4 arcs

* An incomparably more geometrically correct version that is just few bytes longer and GZIP friendly

* Forgot aria label

* Restoring geometric accuracy

* Restoring geometric accuracy
