Editor: redesigned open windows menu

* Scenario names are shown when possible
* Modified maps/scenarios are shown in italics
* Map paths are truncated to filename only (not sure if this is the best thing to do)
* All 'changed' markers are right-aligned
* A red marker means not saved (and will correspond with the italics)
* A white marker means saved/no changes
