Add the Tools > Ban List window

Reimplements the official client's ban list: a searchable table of the
server's bans with Add / Remove / Edit, an own-ban filter and highlight,
choosable columns, and the Add/Edit dialog whose IP and name patterns
can be read as IPv4/IPv6 wildcards, fixed strings or regular expressions
(translated to the regexes banadd takes exactly as the official client
does). Editing is add-then-delete, since the protocol has no banedit.

The ban list is read from the notifybanlist burst that answers banlist,
like channelpermlist. The menu item is only shown where the server grants
b_client_ban_list.

Also fixes ServerModel numbering permissions from 0 instead of 1, which
had every selfPermissionValue() lookup reading the neighbouring
permission — including the group-assignment menus.
