Merge codebase

When I left NESCent, I deposited TreeTapper's code in Google Code ( http://code.google.com/p/treetapper/ ). Subsequent development happened on a privately-hosted version of that code (I was worried about accidentally committing a file with database access passwords). I've since learned a lot more about SVN and have svn:ignored the dangerous files, as well as files that aren't really things to put in version control, such as cached images. Now, changes made on the Google Code repository will be made live on the site. This should make it easier to collaborate with others going forward.

TreeTapper hosting moving

Today, TreeTapper is moving from hosting at NESCent to hosting at the U of Tennessee. NESCent hosting has been excellent (I remember one occasion during a weekend snow storm when NESCent's sysadmin braved Durham's poorly-treated streets and spinning drivers to go in and take care of servers that were, ironically enough, overheating). However, it will be a bit easier for me to maintain if TreeTapper is hosted locally, as I'll be able to directly log in to the production server and change things without needing to worry as much about other sites (though other O'Meara lab sites, like http://www.myrmecocystus.org, are also hosted on the server). So far the move has gone well, now to see if the DNS starts pointing properly. TreeTapper may be down for a few hours while the move completes. MacPorts has been helpful for things like recompiling a version of PHP that can talk to a database.
