Excite Atom button should send a random photon that is absorbable when the atom is in state (2,0,0). #55

Excite Atom appears when stuck in the metastable 2S state. (Excite to n >2 in Schrödinger, will sometimes decay down to 2S state.)

We decided in today's design meeting that:

[ ] Excite Atom button should send a random visible photon (of the 4 possible transitions)
[x] n=2 → n >2 buttons in dialog should always be enabled, even if they are unlikely to do anything most of the time

Also...

[x] The "Excite Atom" button should be visible only when the atom is in the metastable state (n, l, m ) = (2, 0, 0).

Looking at the Java version... It always emits 656 nm (red). But it then selects one of the 4 transitions from n = 2. So that's incorrect and potentially confusing. In the HTML5 version, I'll make sure that the corresponding transition is used for the wavelength that is randomly selected.

This has been implemented, but it's difficult to review, since the Schrodinger view has not been implemented yet. So I'll leave this issue open and circle back later.
