Instead of xdg-open (or open on MacOS), allow forcing a program to open
a message part. The program is determined in that order of priority:
1) If :open has arguments, they will be used as command to open the
attachment. If the arguments contain the {} placeholder, the
temporary file will be substituted, otherwise the file path is added
at the end of the arguments.
2) If a command is specified in the [openers] section of aerc.conf for
the part MIME type, then it is used with the same rules of {}
substitution.
3) Finally, fallback to xdg-open/open with the file path as argument.
Update the docs and default config accordingly with examples.
