show the error string in the GUI rather than stderr

Browse source 
This makes the error string just be an internal "membuffer", which the
GUI can fetch and show when errors occur.  The error string keeps
accumulating until somebody retrieves it with "get_error_string()".

This should make any write errors actually show up to the user.
