No more PHP4

Although stated otherwise before I have now decided to discontinue the support for PHP4.

Just now I have released my template-class, the first class that cannot directly be ported back to PHP4 and that made me rethink my position on PHP4.
I think many of you will agree when I say that OOP in PHP4 is a feature, but not a concept.
The concept of OOP started to get more solid in PHP5, with a much wider support for classes.
PHP6 will most probably follow that road and give even better support, but who knows, right?

Another reason why now I stop doing this is because by now really every hoster should have found the time to migrate to PHP5.
I know not all have, but I think they're the minority.

Well, the result of this decision is this:
- In case I update a class I might not update the PHP4-version.
- I will rename the packages, the PHP5-version will no longer carry the suffix PHP5.
- New classes will only be released for PHP5.
- If for some reason I happen to port a new class or an updated class back to PHP4 I will release it. But don't count on it.
