Adding inline support to coffeekup

gistfile1.diff

commit dc175e2a03a27cac22a70e99d1784018491f0751
Author: Colin Thomas-Arnold <colinta@mac.com>

    added '.inline' to all tag functions.
    
    Usage: p "This text could use #{strong.inline(a.inline href: "/", 'a link')}."
    TODO: It'd be cooler, but impossible I think, to have strong.inline(a href:'/','a link').
