NumberHelper methods should now return html_safe strings (when the inputs are valid numbers or are html_safe). Also adds :raise => true (used internaly) to make the number helpers throw InvalidNumberError when the given number is invalid.

Remove some of the blank rescues from number helper. This makes the code easier to understand, as you're not left wondering what the rescue is actually doing. This does not change documented/tested behaviour.

For performance reasons, you can no longer call html_safe! on Strings. Instead, all Strings are always not html_safe?. Instead, you can get a SafeBuffer from a String by calling #html_safe, which will SafeBuffer.new(self).

  * Additionally, instead of doing concat("</form>".html_safe), you can do
    safe_concat("</form>"), which will skip both the flag set, and the flag
    check.
  * For the first pass, I converted virtually all #html_safe!s to #html_safe,
    and the tests pass. A further optimization would be to try to use
    #safe_concat as much as possible, reducing the performance impact if
    we know up front that a String is safe.
