Reset all dialog custom positions on new Origin session

Version: 2019b

Type: Features

Category: Miscellaneous

Subcategory: Settings

Jira: ORG-19117

There are cases user moved some dialog, script window, etc. to other location .e.g. another monitor and when restarting Origin, user couldn't find them.

So in Origin 2019b, by default the dialog locations will reset. 

Set System variable @RDP=0 to go back to old behavior.
