PyHP Interpreter v1.1

Features added:

• register_shutdown_function
• header_register_callback
• config

Changes:

• reworked caching to use handlers (old code as files_mtime handler)
• optimized parser
• rework prepare file
• now using argparse
• changed directory structure (see pyhp.conf)

This release is currently lacking of more cache handlers, like memcached or redis.
If you wrote a cache handler, feel free to submit it.
