* i2prouter:

- Don't cd to script location, no longer required
    * RouterLaunch:
      - If no wrapper, put wrapper.log in system temp dir
        unless specified with -Dwrapper.logfile=/path/to/wrapper.log
        or it already exists in CWD (for backward compatibility)
      - Append rather than replace wrapper.log
      - Pass wrapper log location to router as a property, so that logs.jsp can find it
    * logs.jsp:
      - Get wrapper log location from a property too
    * runplain.sh:
      - Add path substitution to runplain.sh on install
      - Pass I2P base dir to the router as a property
    * wrapper.config:
      - Put wrapper.log in system temp dir for new installs
      - Pass I2P base dir to the router as a property
    * WorkingDir:
      - Don't migrate an existing install by default
      - Never migrate the data (too hard)
