Fixed print AppleEvent so that Command-P on the desktop would print gnuplot command files. Added more AppleEvents to command file editor. These were AppleEvents supported by WText wrappers that I hadn't incorporated previously. Also added more AppleEvents to pict and moov terminals. Use the Apple Script Editor to view the dictionary of events now supported.
New events support printing, cutting, pasting, editing, etc. of terminals and command files.
A complete rewrite of the find and replace commands to fix several issues associated with them. Previously, if the find and replace strings were identical, the program would go into an infinite loop. In addition, the program did not previously require the current selection to be equal to the find string before performing a replace command. Both of these have been fixed. In addition, find and replace commands now bring the command file window to the front if the operation is successful.
