print, sprint enhancement for context, mime

[o314]

CLOSED SINCE IT WAS TOO BADLY EXPLAINED

Majors points were

• sprint should be able to handle context as a pair, or a vector of pair (may be an union). may be this could be a kwargs splat
• print should be able to handle a mime argument to pipeline to show(io, mime, x) and not only show(io, x). The whole text/$something mime class belongs to print as much as show. Separation is artificial

print is explicitly for text output; I don't think it makes sense for it to accept a general MIME type. For context, there is always print(IOContext(stdout, ...), x), no?

For sprint, you can already do sprint(show, mimetype, x), as well as repr(mime, x), so I'm not sure why we need anything more as far as MIME types go?

Sorry it is very hard to read, i will clean up and repost later if it is ok.
