Have custom actions for certain macros/gadgets

All macros/gadget when displayed in personalized containers (like WYSIWYG or Dashboard) should have these actions: ability to add, edit, delete, collapse/expand + (move just for gadgets).

Some macros/gadgets may attach some extra functionality (or shortcuts) in order to improve the usability and the productivity.

For example:

• display, include - should allow navigating to the referenced entity
• chart, gallery - could offer the ability to download the displayed content
• velocity, script - could have an output switch
• etc.
