Merge pull request #2875 from RosettaCommons/vmullig/nmethyl_update
Updates to N-methyl amino acids
After adding support for spinny N-methyls, the rotamer libraries for N-methyl amino acids need some updates. I plan to merge this after pull request #2855, since that will affect this.
Tasks:
- [x] Update TRP N-methyl rotamer library in database with new version from Tim.
- [x] Update other N-mehtyl rotamer libraries in Git LFS repository with new versions from Tim.
- [x] Update N-methyl atom types and charges:
```
From Tim:
ATOM N Nbb NH1 -0.6046255 0.000 ---> ATOM N Npro NXX -0.7438 0.000
The partial charges should be:
N : -0.7438
CN : -0.2352
1HN : 0.1920
2HN : 0.1920
3HN : 0.1920
```
