Andrew Halberstadt 0e697ce235 Bug 1422302 - Create python/mozterm for sharing terminal blessings across modules r=gps
This is a new module that will provide a place to store some common
abstractions around the 'blessings' module. The main entrypoint is:

    from mozterm import Terminal
    term = Terminal()

If blessings is available, this will return a blessings.Terminal()
object. If it isn't available, or something went wrong on import,
this will return a NullTerminal() object, which is a drop-in
replacement that does no formatting.
