Message:

[Branch 1.5] Implemented MySQLi over the old MySQL PHP extension. This is supposed to be somewhat faster.
Need to test the speed before and after, with DB_CACHE off.

Also made appropriate changes throughout the core classes.
Stripped down some 2000+ lines of code from SimplePie that had to do with caching to database.
removed a single line from an unused part of Inspekt/Inspekt.php that came out ugly after running the MySQL to MySQLi converter script found at http://forge.mysql.com/wiki/Converting_to_MySQLi
Fixed init_database function in install/install_functions.php to use the Database class instead of the old EzSQL class. What a leftover! ...brought up memories!
Renamed the READ_ME.txt to README.txt :)
