Unprefixed line-clamp

[BenjaminAster]

Description

The line-clamp CSS property still needs a -webkit- prefix and some additional non-standard properties (display: -webkit-box and -webkit-box-orient: vertical) to be set in Chromium, WebKit and Firefox. Chromium is currently working on implementing the unprefixed property. Implementing this new standardized property, which differs significantly from the old non-standard -webkit-line-clamp property, likely needs a lot of work from an implementation standpoint.

---

This issue is one of seven issues regarding unprefixing CSS properties/values, originally all in #702 (as per #702 (comment)). The aim is to group the properties together into multiple (but not seven) focus areas.

If this goes through it should only be for line-clamp and not the individual sub-properties yet (max-lines, continue, etc).
