fixed annoying version check

[hx-markterry]

What does this PR do? (please provide any background)

When you install the ui-toolkit as a dependancy you receive the following warning:

npm WARN engine ui-toolkit@0.28.1: wanted: {"node":">0.10 <0.12","npm":"~2.14.8"} (current: {"node":"0.12.9","npm":"2.14.9"})

This change allows node 0.12 to be used without warning.

What tests does this PR have?

No tests as its just a tooling change.

How can this be tested?

Change your package.json to use this branch rather than a set version and you should not see the above version when you npm install.
