2.3.{0,1,2} no longer installs on older npm versions

[dougwilson]

This is a new issue to continue discussion around this (previous #1867 and #1868). There were multiple attempts to fix this regression in 2.3.x, but there is still an issue. The currently known issue is the jade upgrade: jade was upgraded in 2.3.0 up past a major breaking version, which dropped npm supported versions.

@boneskull had some thoughts on what to do here: #1868 (comment)

Proposed fix for patch release: #1888

[dasilvacontin]

Reverted jade in master via #1888.

Thank you, the current master branch installs fine on the older version of npm. Looking forward to the next mocha release :)

@dougwilson I trust you'll let us know of any similar issues in the future. I can't guarantee Mocha v3 will keep the contract, but I'd like to ensure v2 will always work with npm pre-v1.3.7. thanks for taking the time to let us know about the issue

Thank you, @boneskull , will do! I do not mind if you drop the support in v3, as you'll want to make progress at some point and eventually I can stop caring about these machines and update as well :)
