Blitz templates 0.5.1

Blitz templates is a fast template engine written in C and compiled as a PHP module. It started as a php_templates replacement, but developed into much more.
The project is based on extensible template controllers (custom view classes in PHP) and weakly-active templates (simple logic in HTML).
Enhancements:
- Lot of code cleanup was done.
- The "parse" and "include" methods were improved, and their "vars" argument is not a globals array anymore; now its just an arbitrary iteration set and both methods comply with set/block/fetch.
- Templates included by the "include" method from PHP code inherit globals from the caller automatically.
- Corresponding tests were updated.
- A new article was added to the documentation: "Quick Geek Blitz Tutorial", which is addressed to those professionals who want to learn API basics in a minimum of time.
