Implement yajl.to_value() in C, add some more tests, improve the

documentation, and fix some bugs.

 * Check for "not ok" output which now results in test failures.

 * Make yajl.null a full user data so that in string context it will
   be the string "null".

 * yajl.parser():value(value, type) type parameter was always
   "integer" for numerical values.  Instead, it is now always
   "number" to better express the type of the value.

 * coerce object keys into strings before calling js_generator_string
   so as to avoid getting an error about a non-string argument.

 * yajl.generator() simply did not work since the meta-table __index
   meta method was not set, so we now set that meta-method.

 * yajl.generator() had an off by one bug that would cause it to error
   when passed a printer argument.
