1. Added new STL of the Einsy-base as a variant without the fixed raspberry

cover, instead you could print the raspberry_cover.stl for the clip-in
cover.

2. In all .scad files that have a revision stamp in it a variable "rev" in the
beginning of the code was introduced and used in the 'text' functions
instad of using strings directly.
Exapmle:
	rev = "R3";
	text(rev, font = "helvetica:style=Bold", size=6, center=true);

3. In the Einsy-base.scad a few commented lines were added to load the
removable raspberry_cover.stl for referenc purpose, and comments on
which lines were commented to produce the Einsy-base_no_raspy-cover.stl.
Therefore the Revision got bumped to "R3a".
