README.md says to point Slack's slash command at /handle instead of /switch

[Andrew Gray]

After following the original instructions, I wound up seeing an "Unsupported story" exception whenever I did a /slashcommand enable in Slack. From what little I understand from digging around in the code, it looks like Slack should be pointed at /switch instead of /handle. That seems to have worked for me, anyway.

Thank you for reporting this. It has been fixed now. :)
