Initial version 1.0

This is the initial 1.0 version for historical purpose. It was not a maven project. It was simply release as a XAR to download on e.x.o.
Large refactoring to comply with best practices and support latest XWiki versions

- fix issue with Prototype JS not recognizing the select expression
- allow using any macro without requiring the other ones
- improve documentation
- move all macros to their own space
- add a WebHome
- use XAR 1.1 format and cleanup XML
