swapper: Make quotes optional in key-value regex

Browse Source 
The regular expression describing the tmux user options expects to find
quotes around the value. However, in at least tmux 3.0a the
`show-options -g` command doesn't display quotes around the values,
which means the regex fails.

For example, the current regex will fail to find these user options:

	$ tmux -V
	tmux 3.0a

	$ tmux show -g | grep -E "@thumbs"
	@thumbs-bg-color default
	@thumbs-fg-color green
	@thumbs-hint-bg-color default
	@thumbs-hint-fg-color blue
	@thumbs-select-bg-color default
	@thumbs-select-fg-color green

Make the quotes optional so that these options are picked up.

Fixes #33
