The list is now stored in a class variable. Should be easy to 
override/expand this.

This is supported by using sub-arrays:

$requiredModules = array (
	'SPL',
	'zlib',
	array (
		'mssql',
		'mysql'
	),
	'pcre',
);

If the check encounters an array it will check if at least one of the 
items is present. If not the items in the array will be presented with 
the message that one of them is needed.

How to test
-----------
Remove one of the needed modules, or

Add some fake items to the array:

$requiredModules = array (
	'dummy',
	array (
		'plaap',
		'blarg'
	)
);
