Feature/109

This PR adds a TDAF-compliant Conversion Pattern to log4j, including a transaction id. The README and some templates have been modified accordingly.

The issue #109 will be completed when all the traces are revised; this is necessary to create the alarm conditions table.
In addition, adding +1 to bootTimeMilliseconds may lead, if starting with `999` to a 4-digit count (of course, after 10^10 transactions).
