Fix up poor edge-case handling of pagination offsets when changing groups or
filter options. Fix pagination on bulk domain page.
Required:

• reordering pagination/offset/filter munging to/from %webvar and session yet again
• re-adding the offset if we're on a live record list page
• fix call to $dnsdb->getDomList() for bulk changes (offset missing completely)
• explicitly fork $uri_self for group tree, and explicitly trim offset
• remove old code that only handled a limited subset of cases (letter filter and search)
• fix call to $dnsdb->getDomList() in listzones() to use the global $offset instead of blindly obeying whatever might be left over in $webvar{offset}
