Adds bindAll to methods excluded from no-unused-result

[dfadler]

Resolves #35

• Adds a new constant for methods that cause side effects
• Uses side effect methods constant instead of for each constant in no-unused-result

Sounds good to me :)

I'll add a note to the docs and add tests on top of this.
I'm not sure when I'll release this, as breaking changes occurred since the last release. I'll try to do that tomorrow or the day after.

Thanks a lot! :)
