Renamed and moved the log4j xml to the proper location in gemp-lotr-server to be found on startup. Added the log folder to gitignore. Put references to log4j in all project pom.xml files.
Cleaned up and simplified all docker files to remove all commented-out lines (now that they are in VC). Removed obsolete files. Cleaned up the readme.txt to make all the specific steps clearer and to remove excess chatty language.
Created a docker-compose script with 2 containers, one for the app/web, and one for the db. This will in the future ideally be split into 3, one each for app/db/web, but baby steps. Committing before I accidentally break it again.
