SQOOP-78. Consolidate web-based documentation and tarball documentation.

Eliminates "webdocs" target from build, merged with "docs" target.
Web-based format for document delivery is used for local documentation as well.
Links to release notes, API documentation added to documentation homepage.
Release notes are generated for non-SNAPSHOT builds as part of "package" step.
