This adds the "history", "blame" and "raw file" links to the blob page.
You can see them in action for example here:

https://got.omarpolo.com/?action=blob&commit=6595d7300a0803b0372c4bae0ee3a077e4739f59&file=Makefile&folder=&path=got.git

To be fair, I don't really like adding the "Action" line to the header,
but I didn't had a better idea where to put it, and these links are
useful to have.

regarding the diff, the potentially scary {{ " — " | unsafe }} is
actually safe ;-)

template(1) implicitly removes the leading spaces, so having just
— on a line would put it attached the links, hence I have a few
{{" "}} around to make sure there are spaces.  | unsafe is to disable
the html escape that {{ ... }} would otherwise do.  Overall, it's
equivalent to {{" "}}—{{" "}} only maybe less awkward to read?

(I still think that trimming whitespaces wasn't a bad idea overall,
however it has its shortcomings.)
