[dev] [st] add -c option to change class

[Gregor Best]

Hi list,

fueled by the recent bunch of patches to st, I gave it a try. One thing
that was missing (for me) was being able to set the class of the st
window. I use that for matching terminals running different apps to
different tags so I can have an ssh session running irssi at the 'chat'
tag or running mutt at the 'mail' tag.

Note that this is my first try with hg (I'm more used to git) so please
forgive me if my patch is somehow mangled or malformed :)
