* src/linuxsampler.cpp: tidied up a bit, "initialization completed"
  message shown only after the server is actually running
* src/testcases/: print the name of each test suite before running the
  tests of the suite, added first tests against the LSCP server using a
  socket connection to the LSCP server (tests for the following LSCP
  commands: "ADD CHANNEL", "GET CHANNELS", "REMOVE CHANNEL")
