This lifts the requirement of needing to disable the dependencies by
hand if you don't have them installed.
It also enables us to have a single package, that works for all.
gLib will not immediately run the callback after the timeout has been
added.
This caused everything to be a few ms late.
Now the timeout will trigger early by default.
Also added an example line to the config at data/config.
Config syntax is: "WorkspaceSymbol-[workspace_number]: [symbol]".
If no default is provided it will default to the circle with dot.
