hgweb: make viewing of non-text work in hgweb
We use mimetypes.guess_type to guess file types and util.binary to determine
whether a file is displayable as text.
This lets us display displayable text files in our normal source view.
Files that appear to be binary will be displayed as something like
"(binary:image/gif)".
Clicking on raw view will send the raw file with an appropriate MIME
type. Thus things like GIFs will now be viewable inside hgweb without
making a mess. Further, things like postscript files that are text
should show source in the normal view and a browser can launch a
postscript viewer for the raw view.
