Implemented a tree browser

[lyrixx]

Not finished yet

I decided to not use code mirror since the repository is
in a read only mode. I will add highligh.js in a second step.

Todo:

[]: Move some code to the theme

Need this PR to work fine: gitonomy/gitlib#32

@alexandresalome can you do a code review ?

I does not like the code in the controller and in the template to render tree.
I have ported every thing from gitonomy.

Why I did not like:

• The controller is a bit fat
• The template need a lot of data (i think the commit is useless, see below)
• The code is very hard to read and totally no intuitive
• I Think there are design issues in gitlib:

  • Move (or duplicate) Commit::getLastModification to Tree::getLastModification (so is should be in the repository with proxy method)

  • :

    $tree = $repository->getRevision($revision)->getResolved()->getTree();
    $element = $tree->resolvePath($path);
    

    is very weird. I don't understand what happen here. Something like $repository->getTree($rev, $path) could be awesome.

What do you think ?

I'll have a look at it by the end of the week

Since I already implemented it for gitonomy, I understand the point of passing lot of information to the template, but every bit of it is required.

I consider it as good-enough to be merged, it's a good start point.

Ok.
But about

$tree = $repository->getRevision($revision)->getResolved()->getTree();
$element = $tree->resolvePath($path); 

Can we do something ?

I did not try gitonomy, but we should move the git profiler to Gitlib\Bridge\Symfony to make it work with silex.

I think the tree browse use a lot of git call.
