remove ambiguous part about smack-core being the only required
library. It's the only required library of *Smack*, but some user could
understand that Smack itself has no other dependencies. In order to
avoid such confusion, simply remove that part.
Some parts of the documentation still refer to
Connection connection = new XMPPConnection(…)
when it should be
XMPPConnection connection = new XMPPTCPConnection(…)
SMACK-574
Move extension relevant configuration options from SmackConfiguration to
the extension. Introduced disabledSmackClasses that can be configured
via a system property or configuration file.
Separated the reading of provider files from the ProviderManager. Manager now only manages. Added ability to add collections of providers to the manager via a ProviderLoader, of which there is one default implementation which loads from the default file format. Now provider files can be programmatically added at any time. Also updated the configuration abilities so that a provider file can also be set via VM arg, as well as the smack configuration itself. Introduced Java Util Logging as well.
