Modernizr 3.8.0

The nights are getting longer, time to publish a new version of Modernizr to keep the community warm. Besides the usual new feature detects and fixes to existing ones some stuff happened under the hood too:

• First, the build process was converted over to gulp since grunt and especially the test plugins are more or less abandoned. This allows to run the tests under the latest version of node and with all the latest libraries like jquery v3.
• Secondly, for the first time we deprecated two tests: Unicode and Touchevents. The former didnt provide a real value and was more like an educated guess. The touchevents-test is often misinterpreted to test if the device is capable of touch events. But Modernizr tests for browser capability and although it clearly states that even in the test, people opened bugreports once we fixed a test in v3.7.1 that corrected the behaviour in chrome (see #2408) So we decided to deprecate those tests. That means that they are not included in the default build config anymore and their source code will be removed once we have a v4 of Modernizr (whenever that is, no ETA yet)
