  -----------
  [clang-format] Add option for not breaking line before ObjC params

Summary:
>From `clang-format` version 3.7.0 and up, , there is no way to keep following format of ObjectiveC block:
```
- (void)_aMethod
{
    [self.test1 t:self w:self callback:^(typeof(self) self, NSNumber *u, NSNumber *v) {
        u = c;
    }]
}
```
Regardless of the change in `.clang-format` configuration file, all parameters will be lined up so that colons will be on the same column, like following:
```
- (void)_aMethod
{
    [self.test1 t:self
                w:self
         callback:^(typeof(self) self, NSNumber *u, NSNumber *v) {
             u = c;
         }]
}
```

Considering with ObjectiveC, the first code style is cleaner & more readable for some people, I've added a config option: `ObjCDontBreakBeforeNestedBlockParam` (boolean) so that if it is enable, the first code style will be favored.
