e.g., when the engine is not ready

- Move the s60devicerunconfigurationwidget into a separate file,
  add an info button that connects to the device and displays
  CPU/Trk version for testing the connection.
- give TrkLauncher a parent object and an acessor for the device
  description in formatted form.
- Break deadlock when trying to terminate the Windows Trk writer
  thread with bytes pending by using a wait with timeout and
  termination flag.

Removed CPLUSPLUS_BEGIN/END_NAMESPACE and replace CPLUSPLUS_USE_NAMESPACE with `using namespace CPlusPlus;'

these missed the handleExecContinue() callback, so they got missed last
time. added both callback and flag, and some more glue to the gross
isBogus hack.

these are a mess anyway
