[SAC] TracSpamFilter disabled

Due to recent frustration of new users (GSoC students) I've disabled
the TracSpamFilter plugin.

Problem were mostly:

- Legit content considered spam by external services
- Legit content considered spam by bayesian filter

Given the effort we make to accept new users, I've disabled it
alltogheter.

NOTE: configuration cannot be changed from the web at the moment,
      because all trac.ini are not writeable by the webserver user
      (you'd get a forever-spinning browser request)

Shall spam come back, head on to /etc/trac/ and revert the
git commit which disabled the plugin:

   git revert 4186dbbac626aedfb058e462a70389ad8f42aa64

I'd love to make a second round of fixes/upgrades to trac but
have too many things to do at the moment.

--strk;

Additinal info: some instance configurations also had the
spamfilter enabled locally, I removed all those local references
so that all instances now only use the global config.

Shall you want to revert more, all those local configs are
also under a git repository, so:

   cd /var/www/trac/env && git log

--strk;
