Twitter OAuth update

Typical, just as we release the Tweeter plugin Twitter changes authentication method! OK, there was some warning but things have been kind of busy here. Being in Prague without the development laptop - it's getting its poorly hinges repaired - doesn't help things along, either.

I'm working on getting the OAuth integrated into the plugin ASAP, hopefully this week, and an update posted onto the C5 Marketplace.

In the meantime just hold on - not for too long - the shiny revised version will be available really soon!
