Documentation/text on any object in the model (model documentation)

Description:

As an administrator, I should be able to put a text description/documentation on any model object in the settings tab or blueprint. This should include:

• Line items (in blueprint)
• Roles
• Versions
• Actions
• Modules
• Dashboards
• Lists
• Properties
• Subsets
• Line item subsets

Note that I should be able to extract this documentation in a way that it would be useful as an overall model documentation & training tool.
