Created a new version for the configuration file for backwards compatibility reasons
Addressing changes in Brackets that broke compatibility with older plugins:

- Changed usage of the deprecated PanelManager API to WorkspaceManager
- Updated CSS styles that were also broken after upgrating to the WorkspaceManager
- Now events from the Node process have format domainName:eventName instead of domainName.eventName

Running commands is still broken, looks like the communication with the Node instance
is also now broken due to some backwards incompatible changes from the Brackets side.

The commands are actually executed, the problem is that the Node process now does not
notify the UI about them.
