branching off to create new, better testsuite
provide more info about last error in exception message
add generic noargs cmd
properly raise exception from init, fix testsuite
testsuite now knows how to run gibson server
update to latest libgibsonclient
add dummy tests filtering feature.

now you can run parts of testsuite like that:
./runtests.sh test_extension.TestClient test_extension.PyGibsonExtensionTest.test_ping
handle spawned gibson crashes properly
add failing test for unix sockets
Merge branch 'new_testsuite' into initial
