Doc updates.
Add QesCommand::clearMembers(). Both run() and runDetached() should clean after themselves now.
Fix last. Finishing in async mode was not working properly.
Add QesCommand::killAll() and ::terminateAll().
Small amendmend to last.
Remove Qt module designation from #include declarations.
Change private member naming convention from m_varName to mVarName (makes typing a bit easier on certain keyboard layouts).
