DERBY-6680 Other jar files may need to be granted permission to read derby.ui.* properties

Backported from trunk at svn 1620378.

derby-6680-2. This patch moves the reading of the two system
properties up into NetworkServerControlImpl. Other usage of
LocalizedResource is unaffected and might still try to read those
system properties, i.e. as called from ij. This side-steps the problem
so no further permissions need be granted.

Removes the note about LocalizedResource in the policy template file.
