Title: fix for issue # 547 - // block comments on indented code

pull request for [issue 547](https://github.com/jshint/jshint/issues/547)

This update allows for the following if the smarttabs option has been enabled:
```
//[space]if(something) {
//[space][tab]doSomething();
//[space]}
```
... which is the result of block commenting out the following code in some text editors:
```
if(something) {
[tab]doSomething();
}
```
The smarttabs regex is now doing a negative look-behind for a "//" prior to a [space][tab], and allowing it in that case. Test cases have been updated to account for this addition as well.

Please let me know if you feel anything should be adusted. Thanks.
