let rustdoc print the crate version into docs

This PR adds a new unstable flag to rustdoc, `--crate-version`, which when present will add a new entry to the sidebar of the root module, printing the given version number:

![Screenshot of a test crate, showing "Version 1.3.37" under the crate name](https://user-images.githubusercontent.com/5217170/31104096-805e3f4c-a7a0-11e7-96fc-368b6fe063d6.png)

Closes rust-lang#24336

Fix PEP8 style issues in bootstrap code

This fixes PEP8 style issues (other than line-length) in the bootstrap Python code.
