Added new config parm maxAreaCap to restrict the maximum area in the
query parm that can be used.
Added a permissions node logblock.noAreaCap to override this
restriction.
Merge branch 'master' of git@github.com:hannahbrian/LogBlock.git
Changed the code to simply override the area if the user requested an
area larger than the max cap (and they do not have permission to request
a larger area than the cap)
