Stability improvements and general touch-ups

This release improves how aliases are handled by dynamically registering client commands as new alias triggers are added. This means that .help will show all registered triggers. As of now, VS does not allow deregistering commands so aliases will show up even if you delete them. However, they will not be saved and re-logging will remove the dangling triggers.

The next update will probably include dynamic arguments for aliases and a very major refactor of the Alias class to support that.
