Display Names of any UI buttons, fields, etc

The "display name" of any object visible on any web page (e.g. buttons, fields, portlets, widgets, etc) is now added in addition to the "back-end" object name which we used to use, making it easier to understand what area of a web page, the user clicked on.

This closes the loop on displaying any GUI names that an end-user see on a web app. 

And as always, this mechanism is generically built (i.e it is preconfigured for Siebel OUI 8x, WordPress 5.x, and can to be configured for any other web application)
