Added previously missing class selectors cs1-cs7 plaus VA (voice-admit)

Definitely requires my patches to the kernel patches to work (dscp.RELENG_*.diff). OTOH, it is currently broken anyway, so wahtever happens, it cannot get more broken. ;-)

Reasons for inclusion of the missing classes into filter.inc (and not the kernel): 

1. I wanted to keep kernel changes to a minimum.
2. This approach provides a clear point if users need to add their own DSCPs. Yup, two of the DSCP pools are reserved for experimental and internal use...didn't want to add 'em all (2*16 DSCPs) to the list.

Added previously missing class selectors cs1-cs7 plus VA (voice-admit), plus the TOS values which still work with DSCP

Also removed the ranges 1-64 and 0x04-0xfc, which never ever have worked as expected (the kernel code does not recognize ranges nor provide any support for them - just the first number was taken as a single value, NOT shifted into the correct range for DSCP values).

0x10 was removed because it made no sense. If it meant TOS values 0x10 (which is DSCP value 0x04), it could have been TOS lowleday support (which I added, but with correct DSCP value).

Yup, three of the four TOS bits are soft-of compatible with DSCP, only mincost suffered a miserable death due to an ECN bit taking its position.

Archive start is “now” minus archive length.  Not “end” minus archive length.  Sometimes "end" is not "now".
Adjust archives array values to match sizes for average calculation.

Add a checkbox that can be used to request only a IPv6 prefix without a IPv6 address. Some ISPs DHCP6 servers will fail the request if both are requested and only a Prefix is allowed.
