Search strings containing '+' behave oddly

[bran-solo]

Repro steps:

1. Say 'test+poop'
2. Do a '!s +/and'

Expected: Output of 'testandpoop'

Actual: Bot doesn't respond

Probably something weird with how we're using regexes.

Have also seen weird stuff with strings containing question marks. Let me know if you want separate issue.

Hm seeing another one where www.google.com with '!s google/poop' outputs 'http://www.%2A%2Apoop%2A%2A.com/'.

Guessing if we want to keep using regexp in this way we need to escape the input string.

Also fucks up search queries containing '$'

literally just escapt the + like !s love\+/hare- and it will work. I think its funny that bejean wil use a real regex with backticks.
