small suggest: dreamshell svn in github

[zero35]

SWAT i hope put some changes、fixes、wips etc to github when you update your codes，write a compile teaching to tell users how to compile dreamshell svn for users test it and do feedbacks
for example:
svn001
2016-3-1
add patch  for xxx games
svn002
2016-3-2
add new features xxx
svn003
2016-4-1
removed xxx features
i know svn versions maybe not stable，but it will be more convenient to public test before release new version in your homepage
