Default *.min.js to excluded from minification

[Sophist-UK]

Just implemented bwp-minify on my site and had to go through and manually exclude js fles which were already minified.

These fell into two camps:

a. js files named *.min.js
b. js files which were not *.min.js

I would like to propose two possible enhancements:

1. *.min.js files are excluded from minification by default; and / or
2. bwp-minify examines js files just before it minifies them and decides whether they have already been minified. Note: Some pre-minified files are modified post minification to e.g. add copyright comments at the start etc., so determining whether js files are already minified needs to be done carefully; and / or
3. Examine the output js file after minification to see whether it is valid and if not serve the original file.
