Add Maven replacer plugin to insert project version into generated JavaDocs

[Vladimir Dzhuvinov]

This function was part of the old ant build.xml and needs to be reproduced in Maven.

E.g.:

@version $version$ -> @version 1.10.1

I have a feeling there's a way to do this without the maven replacer (which can be finicky), so I'll dig into it.

Thanks. I went through the entire maven-javadoc-plugin documentation and it certainly cannot be done through it (although it would be nice to). So the replacer was the next thing I could think of.

Done with replacer plugin in commit 926d820 .
