new names and symbols for elements with atomic number: 113, 115, 117 and 118

[jgpATs2w]

On June 2016 IUPAC announced new symbols and names (i.e. for 113 https://www.webelements.com/nihonium/).
I've detected the issue in build an atom 1.2.5, but looking at the code the symbols should be updated in this repo, at AtomIdentifier.js, symbolTable. Those are the new lines:

    'Nh', // 113, NIHONIUM
    'Fl', // 114, FLEROVIUM
    'Mc', // 115, MOSCOVIUM
    'Lv', // 116, LIVERMORIUM
    'Ts', // 117, TENNESSINE
    'Og'  // 118, OGANESSON

Thanks @jgpATs2w. @ariel-phet could you please review and assign someone to work on this issue?

Here is a snapshot of the periodic table from v1.2.5 of BAA, which is live on the web site as of this writing:

Here is what it looks like with the modifications in place:

The suggested changes have been made. There is currently an RC under test for Build an Atom, it would be good to get this change into it since it may be a long time before another release is done. Assigning to @jessegreenberg to make sure that this happens.
