/branches/acl

All access to change or "delete" (static IPs aren't actually
deleted unless the whole pool is) should be ACL-ified. Users
without the "c" ACL cannot make changes to existing allocations.
Users without the "d" ACL cannot delete netblocks, routing
allocations, or master netblocks; they also may not deallocate
static IPs. Checks are also done later in the processing to
make sure that a crafted URL can't get around the restrictions.

editDisplay.html required updates to remove form elements from
the static HTML; users that cannot modify content will still
receive a page with some hidden form elements but no submit
button(s) to change or delete content (as determined by their
ACL).
