SOLR-238 - some tweaks to the way site updates and releases happen

[Chris Hostetter <ho...@fucit.org>]

just wanted to send out a little spam to raise visibility on SOLR-238
since we're probably going to try and do a release soon and this issue
would have some impacts on the way both website updates nad releases
happen.

I'd apprecaite it if one or two other committers could read the
comments in the issue, try out the patch, play with forrest and setting
specversion, look at how it changes hte tutorial nad think about how this
impacts site updates and release process.

The goal is to make sure everytime the tutorial.html file is generated, it
correctly identifies what version of Solr it applies to; it's done in a
way that should make it easy to reuse for other future docs (and possibly
other future ant variables besides specversion)
