Improved Release

I'm currently working on a new release. Some of the major changes are:
- "main.class.php" is gone. All that is now in "inc.php".
- "admin.inc.php" is also replaced by "inc.php"
- Ability to change the title 'per-page'.
- Some variables that define the behaviour of inc.php
- Acording to my 'specifications' I changed the name of "templ.php" to "templ.inc.php"
- Improved customization in "templ.inc.php"
- Real usage of $prepath. Now it MUST be defined in every file (eg. './').

Features that I planned, but didn't implented (yet):
- DB portability: Only MySQL is still supported.
- Use of advanced authorization. (No need for this)
- Ability for users to register, and so securing their name (this might be implented soon, but then I will have to re-do the auth-system)
