Steps to Reproduce

1. Go to Macromolecules mode - Flex mode
2. Go to RNA tab at library and open Nucliotides section
3. Hover mouse over any nucleotide to get preview tooltip

Actual behavior

Nucleotide has no IDT alias associated

Expected behavior
Every nucleotide at the libtrary should have IDT alias assigned

Full name	IDT alias
5' Super G	5Super-dG
5' 5-Bromo dU	55Br-dU
5' Super T	5Super-dT
5' 5-Hydroxymethyl dC	55HydMe-dC
5' 5-Nitroindole	55NitInd
5' 2,6-Diaminopurine	5AmdA
Int Amino Modifier C6 dT	iAmMC6T

As per requirements:

7. On preview chemical structure together with name and IDT alias should be displayed.
