Upgrade to Version 0.7!

Version 0.7
-----------

1. Colors are set by using define now, no longer by assigning values to global variables. (As a positive side effect, I deleted about 50 source lines.)
2. Added new color definition for warning messages.
3. Common user messages are stored in a single file.
4. Usernames are now stored unencrypted in the database.
5. Database access information is now stored in a seperate file. -- Repealed
6. New Feature! Installation.
7. Missing database is detected on the index page and an error message displayed.
8. New API functions! display_status_message($statustext) and display_error_message($errortext)
9. Rewrote index.php page to make the post selection and display functions much clearer. Also, the "View next X entries" and "View first X entries" behave a little more intelligently.
10. Added new option to decide how many messages to display on main page.
11. New Feature! Installation on a single database! (You will have to install the code in a new folder.)
12. Avoided stray capitol letters. Honestly, what's the deal with these case-sensitive languages?
13. Integrated in to web page. Basic direction is done via header, website navigation via footer.
14. Database access information now NOT stored in seperate file. Change #5 is repealed.
15. Blog version is stored in the database and updated with the database.
16. New Feature! Changable Options! (Right now, you can only change the number of messages displayed on the main page.)
17. Changed position of Goals Scored message. (A side effect of Version 0.6's login status code.)
18. New Feature! Record of goals scored!
19. Fixed security hole where one installation's login status transfered to anothers.
20. Fixed mistake where all radio buttons on the delete category page would have the "checked" property.
