Allow Linter customization

[kendallroth]

Problem

I can't save the app.css file because I use a property (box-sizing: border-box) that does not pass the Linter.

Ask

Add Linter customization (or temporary ignore) to allow ignoring rules that don't apply or aren't wanted.

Description

As seen below, the Linter prevents me from saving the app.css file to which this belongs because the CSS property is not supported by IE 6/7. However, I certainly don't care about IE 6/7 and would like to ignore that fact, but I am unable to do so currently. This leaves me stuck with a broken app (UI) because I need box-sizing: border-box on all/some components:

Hm, linter should only prevent saving on errors, not warnings... so seems to be something strange going on here. Having a bit of limited time lately, but will look into it as soon as I can :)
