Add ability to generate TestID option for VerificationTest, Test

[drewsteinacher]

In the Wolfram Language plugin for Eclipse, there is a feature that when your cursor is inside a VerificationTest (or Test for the old MUnit system) and hit Ctrl + 1, a menu comes up that allows you to add a generated TestID.

For example, here's a screenshot of the menu:

And when double-clicking (or pressing Enter?) it generates a TestID for the selected test:

This feature would be very helpful when writing tests in IntelliJ, as generating unique test IDs in the same format is painful.

Additionally, the "Add all missing TestIDs" feature would be nice, as you could write several tests, then use that feature to add unique IDs for an entire file with a single press of a button.

Would these features be possible to add to this plugin as well?

Great work on the plugin by the way!
