new feature: allow creation (and removal and managemenet) of ad-hoc networks

[fluxionary]

an ad-hoc network would be e.g. 74.233.215.0/24. adding ad-hoc networks may be useful in controlling specific trolls, w/out impacting all users on large networks (like AT&T).

ad-hoc networks would be read-in w/ the "real" network list at load time.

if they bisect a network, i'm not sure the code can handle it rn... maybe.

ok, verbana can have multiple ip ranges pointed to the same ASN. the only problem will be in sorting the ad-hoc networks into the sequence correctly.
