Add support for specialization in other Archi's features

[jbsarrodie]

See #705 for the core support for specialization and images

This issue is used to keep track of the work needed to make specialization find its way into other Archi's features (excluding coArchi and jArchi).

Here's a list of things to do or check (will be updated when needed):

• [x] User Guide
• [x] Model import feature
• [x] Jasper Report
• [x] HTML Report
• [x] HTML Report (query engine)
• [x] CSV export/import
• [x] Copy/Paste (inside same model)
• [x] Copy/Paste (inside different models)
• [x] Format Painter
• [x] Potential impact on model templates
• [x] Potential impact on Canvas template
• [x] Label Expression
• [x] Conditional Label Expression (needed to reproduce default guillemet notation)

For a better description of each item, see this wiki page

@smileham Where do you think they should appear? Alongside the concepts, or in a separate menu list?

Just saw this:

Maybe as a "third tier" list under the "parent" concept, e.g. under "Artifact > Database (icon), File (icon)"?

I don't think that's possible because a parent menu item is not selectable.
