Add execute/evaluate to TreeEditor

[danielb987]

@dsand47
This PR adds the popup menu item "Execute" or "Evaluate" when you right click (command click) on an action or expression in the ConditionalNG editor.

If you select Execute on an action, that action is executed and a message box is shown when the action is completed.
If you select Evaluate on an expression, that expression is evaluated and the result is shown in a message box when the expression is completed.

This allows you to execute/evaluate only a part of the tree, which might be useful for debugging.

One thing is still missing: If the tree has local variables, these variables are initialized. But the user has no way to change these variables. When execute/evaluate is selected and there is local variables, I will show a table to the user there he might give other values to the variables if he wants to.

Thanks for the PR. Please consider adding a release note in the help/en/releasenotes/current-draft-note.shtml file.

Thanks for the PR. It includes changes to properties files, so the 'Needs L10N' label has been added"

It doesn't currently work to execute/evaluate an action/expression in a Module. But I'm working on that.

Ready for review.

The evaluate/execute menu items work fine.
The Table: for each works. The new dialog structure and descriptions are much better.
