Add config for number of workspaces

Adds NumWorkspaces config, https://github.com/scorpion-26/gBar/issues/45

The WorkspaceSymbols syntax was also upgraded to use maps, since the -n
was hardcoded to query for numbers from 1-9, which is now no longer
correct.
The old syntax for WorkspaceSymbols still works, but only for ws 1-9
