Show models from all opened projects in the submodel dropdown list.

Hi,
This is related to issue OpenPonk/openponk#29
The added code code shows models from all opened projects in the submodel dropdown list.

I'm happy to hear suggestions/improvements to the code.

Hello, great, I think this does what it should. You may also take a look at method flatCollect: which can greatly simplify your code:

bormModels
	^ OPBormDiagramController allInstances flatCollect: [ :each | each editor workbench  projectController project models ]

There are a few downsides:

1. It lists content even of closed workbenchs, until these instances are garbage collected.
2. There is still no way to persist it yet. Each Workbench is basically completely separate and currently Workbench does not allow to have multiple models together, so there is not much of a way to link the submodel to the main one.
   This would require implementing option to have multiple models in one workbench like the OP used to in the video.
3. Whenever there are multiple diagrams of the same model (can be created by "Clone view" button in the middle left part of OP window), it lists the model multiple times (because same model has multiple controllers). This can be fixed by removing duplicities using Set (create the collection as set and then convert to OrderedCollection before returning it), like

bormModels
	^ (OPBormDiagramController allInstances flatCollectAsSet: [ :each | each editor workbench  projectController project models ]) asOrderedCollection

But, if you are fine with these limitation, I have no problem with merging the pull request. Let me know :)

Hi,
Thanks for your tips! I'll experiment with those and probably modify my code so maybe merging is not yet appropriate.
