nickserv/restrict: Fix compilation error

Turns out we needed a struct tm too.  This is what I get for not
checking whether it compiles before committing.
Update libmowgli-2 and contrib module snapshots

This also fixes #79
backend/corestorage: make their_ca_all global again (this was broken when we moved to opensex)
Split out UNBAN flag to +u from +r flag.  (closes #75)
backend: Convert private:templates for +r/+u split.

Fortunately, +u flags were not saved yet so templates will not be damaged
by previous versions supporting +u.
Change the +u (unban) to the +e (exempt) flag.

The +r flag retains all the commands it had, including unban, and access
to add/remove akicks with +f, but loses the akick exemption.

The +e flag allows unban/unquiet on self only (so only via IRC) and grants
exemption to akicks.

There is code to convert old +r to new +re but not code to convert old
+u to new +e.
Add a stub BSDmakefile that redirects to gmake.
help/chanserv/flags: Add new flag +e.
