jsonUnescape skips a character after \uXXXX unicode sequences. #146

For instance, the following code will fail to parse, even though it is valid JSON:
string json_test = "{"a":"b\u221a","c":"d"}";
auto json = parseJson(json_test);

The issue seems to be because jsonUnescape pops an extra character while parsing the unicode sequence, and in cases like the above, that will incorrectly drop the ". In other strings it will instead just skip a character in the output.

The while loop in jsonUnescape has a "range.popFront();" at the end of it that works for all cases except the unicode sequence, which internally pops all 5 characters itself. The logic will need some minor modification (move the trailing pop to each of the other cases explicitly or similar) to avoid this problem.

Good catch. Should be fixed now.
