3573fcca80 design_utils: Set port.net to null when disconnecting 
Without this the python bindings can't actually connect anything else
to a disconnected port since the assert in connect_ports will think
it's still connected

4a9981ee77 pycontainers: Properly handle KeyErrors 
We raise a C++ exception to abort the rest of the execution of
the function.

At the same time we standardize on using a throw runtime error as the
method to avoid warning when not returning values. (some places
used this throw and some other used std::terminate)

Fixes #403

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.
