Updated linter.py to use new inlinesingle reporter

[Several of us](https://github.com/SublimeLinter/SublimeLinter-jscs/issues/6) have been having problems with node-jscs working properly with SublimeLinter-jscs on Windows7+ machines. It appears this is due to SublimeText not managing multi-line output properly on these machines.

To fix this [I've created a new node-jscs inline reporter called inlinesingle](https://github.com/mdevils/node-jscs/pull/348) which SublimeLinter-jscs can use instead.

The new reporter was added to node-jscs in v1.4.0.

I should point out that I've only tested this on Windows 7. It will require testing on Mac/Linux but I can't forsee any issues.
