PHP-Sugar 0.60

PHP-Sugar is a new template engine for PHP, similar in intent to Smarty. A powerful and flexible compilation engine is used which allows for powerful expressions similar to that of PHP itself.
The project also features a clean and easy to understand syntax, which was created with the average designer in mind.
Security is a strength of PHP-Sugar. For example, output is HTML-escaped by default, instead of requiring explicit escaping like PHP itself, which makes it far less likely to accidentally introduce an HTML or JavaScript code injection vulnerability from user-submitted content.
Enhancements:
- The HTML cache was reverted to using bytecode, as the compilation to PHP is too difficult to secure and did not even provide any performance advantage.
- Minor cleanups were made in the parser and runtime.
- Functions can now be called using normal mathematical notation inside of expressions.
- Other minor cleanups were made to the API and error reporting.
- The file-based cache and storage drivers now use JSON if available instead of PHP serialization for cleaner files.
