Small bugfixes:

Ensure reactor not already installed (from pyinstaller created
binaries, reactor is already installed on startup before
pyqt4reactor is imported, causing failure to start. Does not
affect non-binary Qt script run).
Qt reads daemon config flag from DAEMON section not GUI.
Typo in JMQT walkthrough guide.
