Automatic CSS / JS Compression

The elegant and simple implementation (doesn't exist yet) of solving problems with large javascript, css files being sent on every page load.

Instead of
<script type="text/javascript"
src="<inp2:m_TemplatesBase/>js/script.js"></script>

we should use

<script type="text/javascript" src="<inp2:m_Script
file="js/script.js"/>"></script>

Tag Script would:

1. get compressed version of given file based on current theme (compressed
versions could be stored under "/system/cache")

2. if given file was changed after compressed file was created, then create
compressed file with file modification time in it's name and return url to
compressed file

3. if given file wasn't changed after compressed file was created, then
return url to compressed file

There would not be any additional calls to index.php to load every
compressed javascript, because of tag implementation is being used. What
ever compression is made or not could be determined by new configuration
variable. Compression could be turned off automatically, when debug mode is
turned on for example. What compressor to use would be determined based on
given file extension. What compressor engine to use will be determined in
later development stages of this feature (command-line, php, java etc.).

[B]NOTE:[/B]

We should be able to process multiple JS files (and probably CSS) in a single minimized version.

Let's say I want something like this <script type="text/javascript"
src="<inp2:m_Script file="js/script.js|js/another_jq.js"/>"></script>
I did see it a few times like this - can't remember the software /
website, but will find this and put examples here.

Steps to Reproduce:

Need to find good Compress methods for both CSS and JS files.
