This will enforce browsers to retrieve again the file when the hash changes, making sure users don't use old versions of the JS code.
The minify script is changed in several ways, in addition to calculating and appending the hash to the file name:
To revert previous minification, we now use git reset --hard. It's dangerous but prevents the regexp logic from getting too wild.
We now loop through the php files for every js file, making the script much less efficient. Again, this is done to simplify regexp logic.
Explicitly delete source map files from previous minification, to prevent maps with different hashes to pile up.
Fixes #439.
