TISTUD-6940 Content Assist not showing many of the methods and propertie...

Considering that we already fixed this issue temporarily through TISTUD-6920, here we are addressing the proposals based on the Titanium SDK.

For Titanium SDK < 3.4.1, we should not filter out proposals based on static/instance behaviors, as api.jsca file has wrongly categorized them.
With SDK > 3.4.0, as api.jsca has already addressed the static/instance natures of methods and properties, we can do the filtering without any issues.

Added unit tests for Ti.UI properties and methods..
There is no other caller relying on this hacky method. Since it is very specific to 3.4.1 SDK, the method reflects the same. We can make it generic to accept the SDK version.

This hacky code should be going away after couple of releases, so it doesn't need to re-used by any Util classes.
