buxton man pages

I will be pushing initial revisions of a man page set, which will include:

buxton(7)
buxtonctl(1)
buxtond(8)
buxton.conf(5)
buxton-api(7)
buxton-protocol(7)
buxton-security(7)
buxton-layers(7)

In addition, buxton-api(7) will include links to the libbuxton man pages, one for each API function.
