Fix version of JetBrains dependency

- Parent 'com.lyndir.lhunath:lyndir:GIT-SNAPSHOT' enforces dependency
  to 'org.jetbrains:annotations:jar:7.0.2' which is not (publically)
  avaliable.
  Using 'dependencyManagement' of MasterPassword reactor project
  to override version to publically available '13.0'.
Disabled logback configuration file scanning

- When executing from JAR (java -jar) file can't be changed either
- Disabling prevents logback from (certainly fail) try to set up a
  change listener
Changed default log level for Java application

- Default log level for Java application set to TRACE logged users
  master password to console.
  As this equals to STDOUT in default environment one can't be sure
  it's not logged to some system log files as well if not started
  from a terminal session (e.g. a shortcut in a Desktop environment).
  Change makes use of logbacks capabilities to substitute system
  properties with a fallback default.
  If "-Dmasterpassword.loglevel=<LEVEL>" is set during startup
  "<LEVEL>" is used, which can be "TRACE" for testing.
  Otherwise, i.e. if "masterpassword.loglevel" is undefined "INFO"
  is used instead, which prevents master password from being logged.
