The use of printf, wxLogDebug, and std::err/std::out causes excessive
debugging output which makes finding specific debugging messages more
difficult than it needs to be.
There is still some debugging output in test code that really needs to
be moved into a unit test.
Add debugging output section to the coding policy regarding debugging
output.
* ESC no longer closed the window since it didn't properly generate
the close event
* Copy/Cut from a context menu did not work due to a focus-loss issue
* Add better error handling for the copy/cut/paste actions to prevent
text that isn't an FPID from being inserted
