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.
