tigefa4u projects Trac

MultiRepos: Removed `[trac] repository_url` again (introduced in [8431]), as the same effect can be achieved by defining the default repository in `[repositories]` or in the DB.

Related to #1781.

MultiRepos: Avoid issues when copy/pasting repository paths in the repository admin panel. Indeed, the browser includes zero-width and non-breaking spaces in the operation, and this leads to a strange error messaage saying that "<path> is not a valid repository" when it actually is.

MultiRepos: A few small fixes in repository management:

* Fixed an issue with repository URL editing.
* Allow creating an alias as the default repository.
* Fixed an issue when changing an alias to point to the default repository.
* Allow the default repository to be provided by any `IRepositoryProvider`.

MultiRepos: Add the repository URL to the repository metadata and display the link in the source browser.

Closes #1781.

0.12dev: Fixed a regression on Python 2.4 introduced in [8421] (missing import of `any`).

0.12dev: Update the wiki page text in the model ''before'' validation, so that the validation code has access to both the old text (in `.old_text`) and the new text (in `.text`).

Closes #7731.
