CSS/JS minifier in Elxis 4.1

[datahell]

In Elxis 4.1 we implemented a system to unify and minify local CSS and JS files.
2 configuration options where added:
- MINICSS: 0 (dont minify css), 1 (minify css), 2 (minify css and gzip)
- MINIJS: 0 (dont minify javascript), 1 (minify javascript), 2 (minify css and javascript)

Minifier does the following:
1. Unifies multiple css/js files into 1, removes line breaks and comments and saves the final output into the cache.
2. Serves the minified file instead of the multiple files (optionally gunzip compressed)

By using the minifier you
1. Reduce the number of requests towards the web server
2. Reduce the page size (especially gzip reduces the size of css/js even by 80%)
3. Increase the site's speed.

In the screen-shots I attach you can see the page's head without minifier (19 requests) and with the minifier (3 requests).
The external css/js files are excluded. So if you notice the 2nd screenshot you will see that the google maps javascript file was not minified.

Important notice
If you modify a css/js file the minifier won't update the cached file (as it only checks the file path). So you have to empty the minify cache in order for the minifier to re-generate the minified file with your updated file.
