URL params to start from beginning, auto play

[alexcroox]

Would be great to be able to link people to a file and have it start from the beginning of the history (or to be flexible, a specific commit). I like showing the progression of the file, which you can't do going backwards.

It would also be nice to auto step through the history with a user defined interval.

These could be controlled with URL params.

I definitely want to add a specific commit to the url. To go directly to the commit a123 the url would be ...path/to/file#a123.
I also like the idea of starting from a specific commit and move to the selected commit when the page is loaded. For example if we want to start from commit b123, it could be ...path/to/file#a123?start=b123
