New Rule: Indent Map

[Snugug]

Ensure maps are indented when defined in variables

[DanPurdy]

Indentation now works correctly with maps in PR #289

Would a separate rule be necessary here?

[bgriffith]

Could you potentially want to allow or disallow single-line maps? Is that a different rule again?

[DanPurdy]

Hey @Snugug could you confirm what this rule would do. Thanks!

[Snugug]

Yah, the rule would disallow single line maps. The question I have now that I reread this is it should just be in variable definitions or everywhere maps are used (mixin and function arguments come to mind, but that could also reek havoc with indentation rule, maybe)
