Change license to MIT

[hagenw]

I updated the LICENSE using this script.

Could you check, if you agree with the new statement and if everything is ok.

Admitting, that I have only checked a subset of the files, this is ready for merge. For non-merged pull-requests, it would be nice to provide the script for the renaming in order to change the license information for the new files in the respective branches.

You can find them here: https://github.com/sfstoolbox/maintenance-tools

You have to go to the folder and execute something like

for FILE in *.m; do change_copyright_to_mit.sh $FILE; done

and make sure that sfs-copyright-mit.txtis available.
