 * Trigger keypad dialog.
 *
 * $Log: not supported by cvs2svn $
 * 
 * 31    6/15/99 5:33p Matt
 * Fixed small stupid bug.
 * 
 * 30    4/03/99 7:55p Matt
 * Use new keypad update system instead of timer to update.
 * 
 * 29    4/03/99 3:41p Kevin
 * Put in code for "Edit Script" button
 * 
 * 28    3/30/99 4:11p Matt
 * Set world changed flag when trigger deleted.
 * 
 * 27    3/27/99 7:10p Matt
 * Strip leading & trailing spaces before check for duplicate names.
 * 
 * 26    3/23/99 5:52p Matt
 * Added clutter activators for triggers
 * 
 * 25    3/22/99 6:59p Matt
 * Fixed stupid bug:  was assigning UVs to floating trigger face before
 * computing normal.
 * 
 * 24    3/01/99 10:39a Matt
 * Strip leading and trailing spaces from object, trigger, and room names
 * on level load and when the names are entered.
 * 
 * 23    2/28/99 10:40p Matt
 * Check for name already in use when entering a name.
 * 
 * 22    2/11/99 8:30p Matt
 * 
 * 21    2/02/99 11:54p Luke
 * Fixed small bug (MattT on Luke's machine)
 * 
 * 20    1/21/99 11:34a Matt
 * Got rid of portal triggers.  Since we don't have multi-face portals, a
 * face trigger works fine for a portal.  Also fixed a few editor/trigger
 * bugs.
 * 
 * 19    1/15/99 10:51a Matt
 * Disable rename button if no current trigger
 * 
 * 18    1/14/99 11:06a Matt
 * Added names to triggers
 * 
 * 17    1/08/99 2:56p Samir
 * Ripped out OSIRIS1.
 * 
 * 16    10/13/98 3:23p Matt
 * Fixed a problem with the add portal trigger button being enabled when
 * there was already a trigger on the portal's face.  Also, fixed and
 * added some asserts.
 * 
 * 15    9/01/98 12:04p Matt
 * Ripped out multi-face portal code
 * 
 * 14    6/23/98 2:43p Matt
 * Changed calls to OutrageMessageBox() & Debug_MessageBox() to deal with
 * int return value (instead of bool).
 * 
 * 13    2/04/98 6:23p Matt
 * Changed object room number to indicate a terrain cell via a flag.  Got
 * rid of the object flag which used to indicate terrain.
 * 
 * 12    1/23/98 5:54p Samir
 * Added new style script support to triggers.
 * 
 * 11    1/20/98 4:12p Samir
 * New script housekeeping system.
 * 
 * 10    1/15/98 7:34p Matt
 * Revamped error checking when computing face normals
 * 
 * 9     9/24/97 6:18p Samir
 * Use script names instead of script id values to identify scripts.
 * 
 * 8     9/24/97 2:58p Samir
