log4j2, first attempt at a map that switches markers
moved to libAni 2.5
added location for South Korea
updated log4j2.xml, StringUtil now uses a csv instead of a hardcoded list of strings, the location caches now use csv files instead of .txt
added helper class to wrap around Log4j 1.2 or 2

Version 1.2 lacks support for formatted strings without needing superfluous calls, which is solved here, but Log4j2 is preferred
added build.xml to gitignore, as the location of log4j2 is kinda system specific
