Release Name: 1.1.1

Notes:
Maintenance release


Changes:
2007-07-06 (1.1.1)
  * Yui NARUSE <naruse@airemix.com> sent some patches to fix tests for Ruby
    1.9. I applied them and adapted some of them a bit to run both on 1.8 and
    1.9.
  * Introduced a JSON.parse! method without depth checking for people who like
    danger.
  * Made generate and pretty_generate methods configurable by an options hash.
  * Added :allow_nan option to parser and generator in order to handle NaN,
    Infinity, and -Infinity correctly - if requested. Floats, which aren't numbers,
    aren't valid JSON according to RFC4627, so by default an exception will be
    raised if any of these symbols are encountered. Thanks to Andrea Censi
    <andrea.censi@dis.uniroma1.it> for his hint about this.
  * Fixed some more tests for Ruby 1.9.
  * Implemented dump/load interface of Marshal as suggested in ruby-core:11405
    by murphy <murphy@rubychan.de>.
  * Implemented the max_nesting feature for generate methods, too.
  * Added some implementations for ruby core's custom objects for
    serialisation/deserialisation purposes.
