Input: new method select(), passed to underlying input

[sbusch]

New method select which is passed on to the underlying input element. Similar to focus and blur.

Added no documentation and no demo because focus and blur weren't documented/demoed.

Side question: the underlying input is stored in input member variable. This variable isn't officially documented, but defined in TypeScript interface. So is accessing it from outside officially supported and safe, or is this an unsupported feature?

[afc163]

Could you add a test case?

[sbusch]

@afc163 I thought about that, but what should be tested? I could check via selection API if the whole text is selected after select, but then I would have to expose even more methods..

Or - see "side question" above - we should document input as an official feature, which my tests could use (I would keep select() exposed as a convenience method).

[afc163]

Checking select function existed would be enough.

[sbusch]

Just added the test.

Do you / does anyone have an opinion on the "input" member variable?

I need to know this because I need the button to expose a focus() method. I will submit an PR for this after this PR here is done. Depending on an "official" reasoning on such reference member vars, I would introduce (and document) such a member variable for Button aswell.
