Release 0.9.0-beta.0: workspace creation support

All menu switching commands (`switch-window`, `switch-workspace`, and
`switch-workspace-or-window`) can now create and switch to not yet existing
workspaces.  Just type a digit, a name, or `<digit>:<name>`, confirm your
input, and it'll do.  The `<digit>:<name>` format is explained in `man
sway(5)`.  If that format is given, `swayr` will create the workspace using
`workspace number <digit>:<name>`.  If just a digit or name is given, the
`number` argument is not used.
