Add a generic variable chooser widget.

The chooser allows choosing variables from a list, and inserting them into previously focused line edit, text edit, or plain text edit. Variables are now registered with a description in the variable manager. Also make the QT_INSTALL_BINS --> CurrentProject:QT_INSTALL_BINS for consistency.
