[Trac] TracTags release candidate

[Muness Alrubaie]

Hi,

A new release of Trac Tags is finally coming.  This one will include
numerous changes thanks to Alec Thomas of the wondeful TracHacks
(http://trac-hacks.org/).

I'll have to put together a proper changelog, but here are some highlights:

 * Now distributed as a Trac plugin.
 * Completely revamped internals, allowing for multiple tag sources. 
You can now, for example query your tickets based on their keywords (=
tags) from within the wiki (I think someone was asking for something
like this recently).  Additional tag sources can be implemented.
 * Tagging pages is no longer implemented through a macro.
 * More flexible tag querying (unions are now implemented in addition
to the intersections that were there all along).
 * Tested to work on Postgres.

I am looking for volunteers to try out the new release (for 0.9 and
0.10 only - had to drop support for 0.8 now that we're using plugins).
 Installation instructions and precompiled egg at
http://muness.textdriven.com/trac/wiki/tags/Setup (tested on Windows
XP, running 0.9.4, Python 2.3 and FreeBSD, running 0.9.4, Python 2.4. 
Alec runs on 0.10dev and Python 2.4 and TracHacks gets a lot more
traffic than I do, I expect.)

On a different note, the sorted implementation in util.py is bit less
handy than it should be, methinks.  Here's a patch that works (at
least for my needs):

-   def sorted(iterable, cmp=None, key=None, reverse=False):
+  def sorted(iterable, cmp=None, key=str, reverse=False):
      """Partial implementation of the "sorted" function from Python 2.4"""
       lst = [(key(i), i) for i in iterable]
       lst.sort()
