[luau] videl ftp mirror change

[Vince Hoang]

The ftp mirror on videl was recently switched from vsftpd to
proftpd. With this change, class-based bandwidth controls were
added to help give preferential treatment to the UH campus and
local Hawaiian ISPs.

The current bandwidth cap for unknown IP space is capped at
400kbps / 50KBps per IP. If your IP does not fall within the
following netblocks, then your downloads will be penalized until
you send me _privately_ your IP range. Public replies to this
message containing requests will be ignored.

PS. 400kbs is still a _lot_ of bandwidth for a single connection.
