Add a simple syntax for defining anchors anywhere in wiki pages:
{{{
[=#point1]
}}}

The syntax is reminiscent of the syntax used for adding explicit ids to headings:
{{{
== Long title == #title
}}}

It's also very close to the syntax for the corresponding ''link'' to that anchor:
{{{
[#point1]
}}}

Optionally, a label can be given to the anchor:
{{{
[[=#point1 '''Point 1''']]
}}}

For more complex anchors (e.g. when a custom title is wanted), one can use the Span macro, e.g. `[[span(id=point1, class=wikianchor, title=Point 1, ^(1)^)]]`.

Closes #6413.

Added alternative syntax for short TracLinks:
{{{
<wiki:this is the target> or <http://example.org/That page(category)>
}}}

Closes #7386.

0.12dev: Created the default-disabled `tracopt` package, and moved the `authz_policy` component from `sample-plugins` into `tracopt.perm`.

Also, handle the absence of the `configobj` package and log an error in that case.

0.12dev: Ensure that a component "implementing" an interface more than once (for example indirectly through inheritance) isn't registered more than once for that interface.

I would have replaced the use of a list with a set, but the log viewer relies ont he fact that it is registered after the changeset viewer. I'll try to investigate that as well.

Related to #8767.

Added missing svn:ignore '*.mo' on some LC_MESSAGES folders.
