Commented out extra info in php-doc plugin

I commented out this info for the generated php docblocks because I
don't really think that it's necessary since it's provided already in
the function declaration and it takes up extra space at the top of each
function.
Removed quick.sh

This strategy for downloading plugin updates is no longer in use. I'll
have to figure out something else in the future (vundle?)
