Move config from Application Support to Alfred.alfredpreferences
We change the location of the configuration file from
~/Library/Application Support/mr.pennyworth.AlfredExtraPane/config.json
to {/path/to}/Alfred.alfredpreferences/preferences/mr.pennyworth.AlfredExtraPane/config.json
so that the config can be synced across machines just like the rest of Alfred's preferences and workflows.
Fixes #8
