Add option to print critical path source code 
In order to make debugging the critical path easier, add an option that
will log the location each net was defined, if known.
If the file that contains the definition is known, and is readable, also
print the part of the source HDL responsible for the signal definition.

Tobias Müller 659c4fad56 Change version to git describe and make set-able from outside 
Change version to use git describe instead of git log as this will also work
if tags are present and make the version string set-able from outside as a
parameter to cmake, so that package managers can set this if building outside
of a git working tree.
