Enable simulators running under sim servers to know the CWD of clients (ocpirun etc.) (Chris H.)
For the first time, run astyle on code (manually) prior to checkin.

core/container/hdl/src/SimDriver.cxx: send the CWD to the server when loading bitstreams
core/container/hdl/src/SimServer.cxx: receive CWD from client and give it to simulator
 -- also first test of running OpenCPI astyle prior to checkin
tools/astyle/src/ASFormatter.cpp: force { on new line if after "case foo:".
tools/cdk/scripts/ocpiindent.sh: update options
Removed execute permission on sourced env scripts to avoid accidentally running with non-sourced
Added links to run our "astyle" in all environments
