As best I can tell this todo was intended to add workspace movement to
the given output with the `workspace <ws> output <op>` command, but i3
does not behave this way.
This commit allows unquoted spaces in worspace names in order to keep
compatability with i3. The names _must not_ contain the string "output"
which is documented in 'sway.5' because how sway detects the `move
<workspace> output <output>` command. Also I documented that "number"
may be used before the worspace name without affecting how the name is
evaluated.
This implements commands such as:
workspace number 9: test
If a workspace with the given number exists then it will be focused,
otherwise a new workspace with the given name will be created.
