Crowd's Client libraries should be slimmed down to a single JAR file containing all required classes for a Crowd Client

The idea is to modularise Crowd much further than it currently is and remove the poor dependency on crowd-core for our clients.

The end result should be an 'uber jar' that contains all maven modules that have to do with client integration, eg:

1. crowd-intregration-osuser
2. crowd-intregration-atlassian-user
3. crowd-intregration-seraph
4. crowd-intregration-fisheye
5. crowd-intregration-acegi
6. crowd-intregration-jive

And be combined into a single jar file: crowd-integration-client-1.3.jar
