Fixed the way json errors are requested from cargo & rustc #74

Ah, I've also added the code to always redirect errors to Atom from |
Closes AtomLinter#69 Also fixed the way envinronment variables were passed to BufferedProcess -- according to [the documentation](https://nodejs.org/api/child_process.html#child_process_child_process_exec_command_options_callback) (*`BufferedProcess` is actually a wrapper above node's exec*) they should be passed in an `env` subobject of `options`, but they were passed as raw in options object. Adding to these environment variables accordingly set `RUSTFLAGS` variable, when JSON errors are available, makes cargo tell compiler to output JSON errors. When using `rustc` simply providing `--error-format=json` is enough to make compiler do what we want.

Any reason you didn't just use {}?

@Arcanemagus the only reason for this is my poor knowledge of CoffeeScript :) I'll fix this.

Yea, every time I see linters still stuck on CoffeeScript I cringe, I'll get to moving them to ES2015 eventually! 😛

^ This is great for getting readable code out of the CoffeeScript

That's all I see just looking at the code. |
Changed notifications in dev mode.
|
@Arcanemagus I've added a cache for 'ability to have JSON errors', fixed 'new object' stuff and the way dev mode notifications look: It is possible to stack them in one error message, if one would prefer it that way. |
|
As it's already behind a dev mode check, it's probably fine to leave them like that. |

hmm... is this line really necessary?

@gmist This ensures that the cached value is live only for a one lint process.
