Add support for properties and relax support.function regex

[winstliu]

🚨 ⚠️ Do not merge yet! Specs on atom/atom also need to be updated! ⚠️ 🚨

This PR brings back #158 and combines it with #146.

• support.function.dom.js has been kept and is prioritized over the now-generalized support.function.js regex.
• entity.name.property.js now catches anything that doesn't fall into support.constant{.dom}.js and support.class.js

Before:

After:

/cc @bucaran since I know you had some concerns about this
/cc @nevir because this only adds .property for things not already marked as .class and .constant
/cc @Victorystick, @AMalininHere, @pchaigno

Refs #137
Fixes #37
Closes #146

Will this detect functions executed with .call and .apply as functions? e.g.:

Array.prototype.shift.call(arguments);

Going to close and re-open as a different PR to try to slim down the commits (and the fact that git is refusing to sync properly).
