TextKeyBindings
Updated Textbox.lua and DebugConsole.lua to handle ctrl-BACKSPACE (delete to beginning of line) and ctrl-DELETE (delete to end of line) keybindings.
Updated the RandomActor and RandomObject dialogs.
The RandomActor.lua:
autofocuses on the random actor placement button when opened.
Placed actors are full clones for the currently generated actor, with special handling for escorts.
