Updates

First of all I added the text bundle which is basically:

1. A mediator between text transformation providers and consumers, using a white-board model.


2. A utility class library for common text mangling tasks that were spread out over the other bundles.

Then I started to commit the first batches of updates on the Java 5 Language level. E.g. code uses generics and java.util.concurrent.

Last but not least there is a MailService now (part of the system-services bundle) and the userdata service was updated to allow editing, support a review mechanism and provide a mechanism for confirmation of email addresses (on creation and changes; logically makes use of the MailService).

Also new in the repository are some updates and bug fixes as always. Other updates will likely follow up soon.
