Add reaction or command for rerunning typofixed invocation

[fwcd]

Currently, D2 yields an error message if the user misspells a command name:

User: %hlp D2: Sorry, I do not know the command hlp. Did you mean help?

It would be nice, if D2 could offer rerunning the command (with the same args/pipe) through a custom reaction or a custom command.
