Import encodings module explicitly
encodings: initialize all locally available codecs
showart: added auto_mode flag to be more clever about available encodings

When available, the showart function will only respect the input encoding if
the session is UTF-8 capable. If not, it will pass the file data as-is
showart: allow the sysop to configure the default encoding with system.art_utf8_codec
showart: provide a default configuration setting
showart: in auto_mode, use cp437 when on a cp437 terminal
Delete automsg.txt
