String lower

Examples
text = "Hello World"; show_message(string_lower(text));

The above example will change "Hello World" into "hello world". This is good if you're checking what the player has typed in, as "Hello World" is not the same as "hello world". This would mean you would have to check every permutation of 'hello world'. It would be far simpler to change it into lower-case and just check that:

text = get_string("","") if (string_lower(text) = "hello world") { show_message("Hello to you too!") }
