Some tweaks to improve alignment in table with checkbox

1) If a checkbox does not have a description (even if it is empty), layout will be broken as checkbox won't be aligned correctly

2) UPnP checkbox looks better with description instead of help

This commit fixes the two issues...

Allow section header to be omitted by specifying "NOTITLE" as the section title.

Remove a-f from IPv4 address pattern

It seems to me that a through f should not be part of the pattern for the "V4" case.
