making it a proper ZT fork: added ZT repos for deployment, updated Maven coordinates to ZT-specific (until our pull requests are accepted and we can switch back to upstream project)
added "source encoding" setting
Use BASE64 encoder from Apache Commons Codec instead of "sun.misc"
package (which is not the "right way")
removed some unused code and unnecessary annotations+casts
added version 1.3.14
removed latest version number from README, so we do not need to update it for each release; added note about commons-codec dependency
