This commit re-implements `mach pastebin` for use with the new Mozilla pastebin tool (paste.mozilla.org). As with the old implementation, the tool supports passing a file for upload as well as reading content to paste from stdin. `dpaste` (the software that runs `paste.mo`) is supposed to support sniffing the correct syntax highlighter from the given filename, but this feature does not seem to work (both on `paste.mo` nor `dpaste.de`). Instead we have a mapping of known filename extensions to known available highlighters on `paste.mo`. `mach pastebin` will attempt to guess a highlighter from the file extension or the basename of the file if none is available.
