Add a way to set it from the client.
For now, in the Help > About dialog, the L key toggges the logging
level between the default (whatever is set in loolwsd.xml or on the
loolwsd command line) and the maximum a client is allowed to set
(which also can be set in loolwsd.xml or on the loolwsd command line).
Also while at it, uncouple the toggling of the Trace Event generation
from the triple-click tha toggles tile debugging. It is now on the T
key.
Also swap the meaning of "min" and "max" for the logging levels. Even
if the Poco::Message::Priority values are such that the less urgent
priorities have a numerbcally higher value, conceptually it is more
clear to say the more urgent priorities (levels) are "higher".
