Restructure project to use Maven exclusively and bump to v1.0.1-SNAPSHOT

- Remove legacy Ant build system (build.xml, sources/ directory)
- Migrate to Maven-only build with standard directory structure
- Add comprehensive Maven documentation and JAVA_HOME setup for Fedora
- Update pom.xml with exec plugin and bump version to 1.0.1-SNAPSHOT
- Add CLAUDE.md for development guidance
- Update README.md with detailed build/run/clean instructions

-How to add a new protocol:
-
-1. Copy the file VSDummyProtocol.java into VSYourOwnNiceProtocol.java
-
-2. Edit VSYourOwnNiceProtocol.java and replace the classname!
-
-3. Edit the initialize method of events.RegisteredEvents.java and add the classname
-of your protocol.  E.g.: "protocols.implementations.VSYourOwnNiceProtocol"
