www: Make Builder related URLs take buildername

This allow to share user-friendly URLs between users.

Note that using buildername in APIs can be problematic, see #7552.

The problem with builder names in URLs is that builder names can change and then all URLs would break. I will think about how this could be solved. The PR itself looks good and would improve user experience.

I agree that it can be an issue (in addition to #7552).
I looked into this as it was a feedback from users on things they missed since upgrading from 0.8.

But, maybe I missed something, but builderid seem to not be stable either in case of name change right?
I tried with the default sample from a create-master, ran a build then renamed runtests to run-tests and the BuilderId changed.
So wouldn't buildernames be as faulty as builderids in urls?

You're completely right. Buildername has 1:1 relationship with builderid. Which means that there are no blockers for this PR.

Still think merging this should be on hold until #7552 is addressed as this would add onto the inconsistency of which builder can be accessed by name.
