String repeat

Examples
text = "bla"; show_message(string_repeat(text,2)); //this shows 'blabla'

It can also be used to optionally show text:

draw_text(x,y,"your health is "+string_repeat("very low",health<20)+string_repeat("low",health>=20));

That example draws "your health is very low" if the variable health is below 20. If your health is equal or larger then 20 it draws "your health is low".
