Update ACM template.
Add the ACM template for course project write-up.
NOTE: It is of my best to compile the tex file with XeTeX engine. So the
ps files and some other issues could be resolved.
Update project report template.
It is of my best to use sig-alternate for typesetting the project
report. And it is not user-friendly to type Chinese in Emacs (tested
over and over).
