Allow punctuation in redirects

[dariota]

Commands silently fail when they contain a redirect with punctuation, for example &buttcoin tip qi for being a good mathematician and giving up when it's trivial fails (because of the apostrophe) and doesn't message the user.

Proposed solutions:

• Simply allow punctuation in redirects if there's no reason not to
• Strip punctuation from redirects before using them
• Run the command, but without the redirect (eg &buttcoin tip qi it's would tip qi, but send no message)
• Don't run the command, but message the user and tell them why it failed
