Add ability to display names under compounds with RDKit

[mimvoid]

Use RDKit.js's ability to detect a compound's _Name property and display it in the legend. Closes #75.

I looked through smilesDrawer's source code and unfortunately could not find any equivalent. As far as I can tell, it's only possible with RDKit.

Syntax:

C1([Cl])=CC=CC(C(=O)O[OH])=C1 mCPBA

Result:

[Acylation]

Thanks for figuring this out! I'm struggling with my upcoming finals and will possibly reviewing these next weekend.
