Do not minify already minified files

[DarkaOnLine]

Some times JSMin will throw "Unterminated set in RegExp at byte" exception if the file is already minified. See more: http://www.mrclay.org/2013/11/27/jsmins-classic-delimma-division-or-regexp-literal/

Added possibility to exclude extensions from minification process.

@Stolz Any comments on this ?

@DarkaOnLine Sorry for the delay, I'm currently on vacation. I'll review it a few days. Thanks for your contribution.

@Stolz ?

[Stolz]

@DarkaOnLine I'm not sure about this implementation, particularly with the use of loops to compare strings. Do you think you could use a regex approach similar to the one used for the '*_regex' config options?.

If you take a look the current '*_regex' options do not use the file extension to know what to include/exclude. That way final users can have exclude a wider range of options.

Are talking about stringContains method ?

[Stolz]

Yes. I think using preg_match() could do the trick

[DarkaOnLine]

OK. will change it

[DarkaOnLine]

Changed comparison to regexp

(pedant)

. is a wildcard, which matches -.

Perhaps [-.]min\.js$

You are right. Yours pattern even significantly faster:

Time 2: 1.8835067749023E-5

This has been merged. I refactored it a bit and the option has been renamed to no_minification_regex.

Thanks again for your contribution.
