Allow to set the default branch in repo configuration

[pulkomandy@…]

Hello, sorry if I missed this in the documentation. I found no way to set which branch should be used by default when accessing the "source browser" tab.

This adds up to the effect of #10704: in my case the default is to show an internal commit that is not relevant at all here: ​https://pulkomandy.tk/projects/avrstuff/browser/avrstuff and I have to manually switch to the main branch which leads me here: ​https://pulkomandy.tk/projects/avrstuff/browser/avrstuff/?rev=7d84448b6037c7741101861dd6ea66c12c1108c2

I see no way to tell Trac that by default it should show the last commit from the main branch.

Duplicate of #10136. I agree it would be a good feature.

From the linked tickets I found this:

​https://github.com/hvr/trac-git-plugin/pull/13/files

I have applied this patch locally and it works for me. No need to add extra configuration options then, it uses the correct default branch from the git repository.

I don't think we should change get_youngest_rev() to solve this ticket. We expect get_youngest_rev() returns youngest rev. The behavior shouldn't be changed.
