Add Align to align HTTP headers

[arp242]

IMHO this makes stuff rather more readable/scannable. Some people may not like it, so I added it as an option.

Will automatically align to the longest header; I modified the sortHeaderKeys() so we don't need to do an extra loop for it.

Also pass the Host header to printHeaders() so it's aligned too. Do some special-fu to make sure it still prints as the first.
