(* Multi-window editor example by DoDi <DrDiettrich1@aol.com>.

This example application only demonstrates the implementation and use of
multiple editor windows. It does not demonstrate any editing capabilities.

1. Open files from the menu.
2. Drag file tabs to dock edit pages somewhere else.

This is the first working version of dockable SynEdit components.

Done:
+ maintain a list of open editor windows (active window first)
+ open files in the (last) active editor window
