Convert some "Save As" actions to run asynchronously.

This introduces e-shell-utils for miscellaneous utility functions
that integrate with the shell or shell settings.  First function
is e_shell_run_save_dialog(), which automatically remembers the
selected folder in the file chooser dialog.

Also, kill some redundant save dialog functions, as well as some
write-this-string-to-disk functions that block.
