Metadata app: Operations could use some descriptions

[paterczm]

From what I can see, developers are often unsure what is a difference between 'edit entity', 'create entity' and 'create version'. It would help if metadata app provided explanations.

This looks good, though I just realized it will be a wasted effort once we migrate to angularjs: #81. The angularjs version is pretty advanced and much more maintainable... sorry, I should have told you. Would you like to work on the angularjs version?

Hah, oh well.

I've never worked with angularJS before, so it depends on how timely that replacement plans on being. Though, I can probably just add this functionality to the angularJS version if you'd like before we consider this actually closed.

[paterczm]

There is no timeline. I started working on it, but got involved in more pressing issues. Core functionality is already implemented.

See pull request #115 for the vanilla JS impl. This needs to be ported to the angularJS version which will eventually be used in favor of the vanilla JS implementation.
