Display parent link in repos browser. Fixes #2135.

WebAdmin: only display time in versions table if it is set.

Make sure that the min/max depth of the `PageOutline` is within the 1-6 range. Closes #2136.

Add a generic implementation for the recently introduced `Repository.has_node(path,rev)`

If given an argument, the !MacroList macro will only show the documentation for the macro having that argument as a name. Example usage: `[[MacroList(Image)]]`

The wiki engine "state" is now cached entirely in the `WikiSystem` component,
thereby associating it to the proper environment.

This was the original solution for #1750, as implemented in InterTrac.

Fixes #2138.

Inform the user that a `trac-admin ... resync` is needed
if the ''repository_dir'' has been changed since the last resync.

This adds a 'name' property to the `Repository` class (given to the constructor).
This name is ''not'' necessarily the content of `repository_dir`.
E.g. for Subversion, it's
{{{
svn:<the UUID of the repository>:<repository_path>
}}}

Closes #2107.
