Minify_groupUri() doesn't notice changes in file inclusion/order #241

Open GoogleCodeExporter opened 9 years ago

Paul Schwarz noticed that "while it does a good job of checking whether files 
have been *modified* it makes no attempt to notice whether the group itself has 
been modified, i.e. adding or removing sources from the group" (or re-ordered).

i.e. GroupUri needs to append a hash of the array of filesnames along w/ the 
max timestamp. Here's what I recommend:
* always starts with "0" so RewriteRules doesn't need to change
* md5(serialize(array(filenames) + array(maxTimestamp)))
* output MD5 in base64 and strip +/=

This won't work either. Including full filepaths and mtimes is the only way to 
catch modifications. On the plus side it won't make MD5's output longer.
