CSSTidy Code

Changes for CSSTidy 1.2 final (PHP) and Chinese translation (thanks to Liang-Bin Hsueh)

- added seperate selectors feature to C++
- added a timestamp feature to C++ and PHP

- Fixed a bug for PHP4
- Corrected settings for C++

Improved interface for the web interface of CSSTidy. The PHP version should now have beta quality.

Additional to that, all commit messages like this one will (or rather should) be sent to the mailing list from now on. So all subscribers get a deeper insight into the development process.

- fixed random fime name in css_optimiser.php
- fixed crash and optimisation bug in merge_selectors() (hopefully)

PHP: Seperated optimising from parsing

Fixes and various code improvements.
Yet to be updated are the templates, then the new preserve_css mode should be quite finished.

Fixed bugs (PHP): Missing indent in @-rules and automatic deactivation of some settings when preserve_css is enabled

New feature: Preserve CSS (+ many code improvements)

This needs more work of course, C++ incomplete, bugs left in PHP.
