Full function-hooks for rules (implemented)

[Bulle]

There are many more zone hooks. They are implemented in hero_zone_Hooks.cpp, which generates the hero_world.dll shared library.
I removed a couple hooks of mine as they rely on other non-hook related changes on my server.

Those custom hooks are of course only there as examples. You do not want them on your own server

Now you can probably understand why I was so quiet about the topic
This code submission is quite huge, I will understand if noone can find the time to try it out (especially as I may have introduced errors when porting the code back to CVS from my SVN repository, and weeding out the other unnecessary change I made).

If I make other interesting changes to the server I will make sure to post them somewhere else. Now after all this effort it is Zebu server time
