Proposal: Extend max line length to 100 

Just throwing this out there. PEP8 says

> For code maintained exclusively or primarily by a team that can reach agreement on this issue, it is okay to increase the nominal line length from 80 to 100 characters (effectively increasing the maximum length to 99 characters)

Reasons:

- more informative variable/className/function names are generally longer, and I often find that they drive a single statement onto multiple lines, which IMO is harder to read. Having a max line length makes a lot of sense, but I think we should expand it a bit.
- we're not working on 1024x600 screens anymore. Below is a screenshot of my workspace, with 4 files side-by-side, and enough space to comfortably fit 120+ chars on a line.
