MapPatcher.jar can now take a user-defined tile line when conflicted.
Added a clean_map_git.sh file that will automatically clean maps
without needing a prepare_map.bat call beforehand. Needs to be run in
git bash, or have .sh associated with something that has git.
Fixed line endings in install.txt to show up right in notepad.
