Convert junk filtering EPlugins to EExtensions.

We now have a proper junk mail filtering API.  All junk filtering
extensions must subclass EMailJunkFilter for user preferences and
availability testing, and implement the CamelJunkFilter interface
for the actual junk filtering and learning operations.

The bogofilter module should be feature-equivalent to its former
EPlugin.  The spamassassin module is far more complex.  It's nearly
feature-equivalent to its former EPlugin, but I ditched the spamd
respawning code since it seemed unnecessary for a mail client to
have to deal with.  If there's a huge outcry from users about it
I'll reluctantly put it back, but I don't expect one.

This gets us a step closer to killing off EConfig, and eventually
the EPlugin framework itself.

-Bogofilter plugin for Evolution
-
-This plugin implements junk filtering for the Evolution mailer,
-provided by the bogofilter utility. Bogofilter (http://www.bogofilter.org)
-if a fast and nimble mail filter using a so-called Bayesian technique to
-classify junk and non-junk email.
-
-CAVEATS:
-
-For Evolution versions before 2.5.2, the definition file for the stock
-junk filter plugin, 'org-gnome-sa-junk-plugin.eplug', must be removed
-from the plugin directory to avoid conflict with any alternate junk plugin.
-Simply disabling the SA plugin in the configuration won't help.
-This is due to a flaw in the loading code for this hook type
-(see GNOME bug #313096).
-
-To be able to classify emails as spam, bogofilter needs to have some
-messages in its ham (non-spam) wordlist. This presents something of a
-chicken-and-egg problem for Evolution, because it can feed messages
-to the junk filter for learning as non-junk only after these messages have been
-classified as junk and moved into a junk folder (GNOME bug #322105).
-Thus, if you haven't got a pre-existing bogofilter database, you may need
-to feed it some messages known to be non-junk, using its
-command line utility:
-
-bogofilter -n < saved-ham-message
-
-Alternatively, you may use Spam Trainer, which is a GUI tool that supports
-drag-and-drop from Evolution:
-
-http://spamtrainer.sourceforge.net/
-
-Set it up to use bogofilter commands for training:
-  Ham command: bogofilter -n < %f
-  Spam command: bogofilter -s < %f
