Release 4.0

4.0 is the first real Sloeber release. Not only is there now a Sloeber github repository but all baeyens.it references have changed to sloeber.io
This means that for eclipse V3.1 and V4.0 are completely different.
You can (but should not) install V3.1 or earlier and V4.0 and later in the same eclipse instance. It may be fun for some time but that won't last.
New and noteworthy are:
-adding lots of other boards
-added support for debugging
-improvements to ino file processing: extern C, defines before includes,classes
-rename scope to plotter
