7.0/fix about tab (#232)

* Fixing case of non-string hash

- If the About tab is the first tab clicked, and the browser is Chrome then the
  hash passed to this function was: null. This would cause the function to error
  out when attempting to regex match against it. In Firefox the value provided
  in the same situation was: 'null'. Which allowed the 'match' function to not
  error out. This small change just coerces the value of 'hash' to a string if
  it is not already.
