Various minor changes

Covers:
* https://github.com/KSHSK/WAVED/issues/82 - Move link on application to github
* https://github.com/KSHSK/WAVED/issues/189 - Don't display auto-actions in Event dialog
* https://github.com/KSHSK/WAVED/issues/132 - Reconsider Workspace as a Component

For the last one I renamed a lot of variables and functions, so there's potential for error. Let me know if I missed anything.
