Issue 9/add git no optional lock (#10)

* Update README.md

s/GiTmux/Gitmux

* Bump gitstatus

By bumping gitstatus to v0.4.2 we're now calling git with
GIT_OPTIONAL_LOCKS set to 0, ensuring gitstatus does not lock the
working tree for its operations, effectively giving higher
priority to user-initiated operations. This is useful when gitmux
is run in the background.
