Make All Links Permanent

[sunjay]

All over the code documentation we have links like this:

turtle/src/turtle.rs

Lines 62 to 64 in 1476e1a

	///
	/// 
	///

Or this:

turtle/src/turtle.rs

Lines 680 to 682 in 1476e1a

	///
	/// 
	///

The problem with linking directly to master or gh-pages is that those links will break if we ever move the files or put them somewhere else. Instead, we should link directly to a ref that contains those images.

Instructions

1. To do that, go to the GitHub page for each image
   • e.g. for https://github.com/sunjay/turtle/raw/master/forward.gif, the GitHub URL is https://github.com/sunjay/turtle/blob/master/forward.gif
2. Click on the short hash for the latest commit and copy the full hash from the URL
   • e.g. for forward.gif, the short hash was 17bf90d and the full hash was 17bf90d65abf51bb46549bf5036c8f284ed1b4de
     
3. Replace master or gh-pages in the original image URL with the full hash
   • e.g. for forward.gif, this results in https://github.com/sunjay/turtle/raw/17bf90d65abf51bb46549bf5036c8f284ed1b4de/forward.gif
4. Test that the link still works
5. Replace the link in the source with the now permanent link

There may be other non-image links too that link directly to master or gh-pages. These should all be updated.

• Delete gh-pages branch once this is merged
