Make a new release for eXist-db 6.4.0+

[tgraham-antenna]

The current 1.1.4 release does not work with eXist-db 6.4.0. I had to install Maven and then build my own snapshot to get a working versioning module.

Since I was updating from eXist-db 3.0rc2 to eXist-db 6.4.0 (i.e., a long time after I set up the previous database), the sequence was more like:

1. Find that versioning wasn't happening
2. Confirm in the documentation that the collection.xconf syntax was still correct
3. Search the documentation to find in the eXist-db 3.0 release notes that versioning is a separate module
4. Install version 1.1.4
5. Stack traces
6. Grep the jars to see if the unfound method is a classpath problem
7. Search the eXist-db source code and commit history to confirm that APIs have changed and when
8. Clone the xquery-versioning-module Git repository
9. Install Maven
10. Build the module
11. Install the module
12. Versioning is working

hello @tgraham-antenna and welcome back. 3.0.0-RC2 has been a while, I ll look into the versioning module and see where we are at with newer releases. Good to know that it is working after you did a local build.
