* add more module handlers:

* add more module handlers:
  * start (alloc structures here; don't depend on others...)
  * init (fill your structs, register with others...)
  * shutdown (free your static structs etc.

  * Session New: for allocation etc.
  * Session Attach: on each request before it gets hot.
  * Session Detach: clean up your session local stuff
  * Session Destroy: the user is gone; flush your memory.

* more news: WC is set before the SessionNew; so you can use WC there.

* shuffled some more stuff arround:
  * i/o related stuff
  * directory calculation
  * local css detection is now part of the start handler...
  * all creates/frees of structures that can be done in the above handrlers is done there now.
