Include Pancake version in Moody build hash
Partial port of Pancake from PHP to C

This commit introduces the following changes:
- HTTPRequest class, MIME class, invalidHTTPRequestException class and
some core functions completely ported to C
- All headers stored and treated case insensitive
- JIT creation of superglobals (PHP 5.4 only)
- Updated Moody
- Improved output handling
- Warning: Old custom exception handlers might crash the worker as
HTTPRequest::$answerCodes was removed - Use
HTTPRequest::getAnswerCodeString(int $code) instead
- Deprecated: invalidHTTPRequestException::getHeader() is deprecated now
- property "header" can be directly accessed
- Moved compiled sources to sys/compilecache/
- Short note on startup when sources need to be compiled
- Graceful shutdown of RequestWorkers (will shutdown after all pending
requests are finished)

Reasons why you should NOT USE this version:
- Some features (HTTP authentication, multipart/form-data) are missing
- Probably contains many bugs
- precondition broken again
- Might be unstable in certain cases
- Could have some security leaks
- Leaks memory (Use Zend debug builds for leak information)
- Does not run with PHP 5.3

If you want to test this commit in a somewhat safe environment, you're
welcome. However I'd absolutely not recommend it for production servers.
Run compile.php to compile PancakeBase for your system (requires build
toolchain).
