build: centralize FlossWare dependency version management

- Add properties for all FlossWare dependency versions
- Update dependencies to use ${flossware.*.version} properties
- Centralizes version management in one place
- Easier to update all FlossWare dependencies together
- Follows Maven best practices for version management

Properties added:
- flossware.jcloudstorage.version=1.0
- flossware.jfiletransfer.version=1.0
- flossware.jmessaging.version=1.0
- flossware.jcontainer.version=1.0
- flossware.jvcs.version=1.0

Benefits:
- Single source of truth for dependency versions
- Easier dependency updates (change one property)
- Better maintainability
- Consistent versioning across all FlossWare libs

Fixes #72
