Write REPL history to file

[geigerzaehler]

The REPL input history is never written to the configure history file by haskeline.

The reason is that haskeline only writes the file if the InputT monad exits properly, that is without throwing an exceptions. At the moment the radicle binaries only exit on Ctrl-C and EOF. Both cases throw an exception.

I don't think that's the problem. The issue is that the executable doesn't write to the file if the file/dir don't exist.

Indeed it works if I do mkdir ~/.local/share/rad. Can we change the getHistory function to ensure that the directory exists?
