Add more consistent events in the editor 
This introduces a much more consistent set of events within the editor
for whenever a element is added, removed or modified.

The events emited on the `RED.events` event system. The event names
take the form: `"<thing>:<action>"`.

`<thing>` can be one of:
 - nodes
 - flows
 - subflows
 - groups
 - links

`<action>` can be one of:
 - add
 - remove
 - change

The payload of the events is the object in question.

There is also:
 - flows:reorder    - when tabs are reordered. Payload is array of flow ids.
 - workspace:clear  - when the workspace is emptied - part of switching projects

The `nodes:change` event was already used by RED.nodes.dirty() to cause
the Deploy button to become active. This renames that event to:
 - workspace:dirty  - Payload is boolean flag for the dirty state

This commit also updates the Palette to use the subflows:change event to
only redraw subflows that have actually changed rather than refresh them
all whenever one of them *might* have changed. This removes a noticable
flicker of the icon which was needlessly being redrawn.
