Clarify HTML snippet for the creation of the "Loading ..." row by using less jQuery API

Doesn't work with old versions of Opera (syntax error for `/\$.../`).

MultiRepos: rework r7964 - keep possibility to notify using the repository dir, but also support having multiple scoped repository defined on that base repository.

A bit like what `get_base` does, but focused on the simplicity of re-using the REPOS info available in the hook.

MultiRepos: if one wants to keep the auto-enabling of the trac.versioncontrol components, the `repository_dir` has at least to be ''present'' in the `[trac]` section (it can be empty, as per r7970).

MultiRepos: as changesets can be present in multiple repositories, the timeline event shows the list of repositories where the corresponding changeset can be found.

MultiRepos: make it possible to work without a default repository (i.e. when `[trac] repository_dir` is empty)

MultiRepos: add more TracAdmin `repository` management subcommands

- `add`/`remove`/`rename` a repository
- create an `alias` to an existing repository
- `list` existing repositories and aliases

Patch written by Remy Blank on #7822.

MultiRepos: fix changeset view option panel, integrate `reponame` in the paths

MultiRepos: move `diff_options_fields(diff)` out of macros.html into diff_options.html snippet.

MultiRepos: fix a few changeset related links

MultiRepos: add sync command (i.e. resync without initial clean-up).

This is very useful for resuming a resync that has been interrupted, without restarting it all over.
