Fixes issues with pen bbcode. Replacetext did not work correctly after I changed text2list - (It was missing 'needles' at the beginning of 'haystacks').

>dd_replacetext and dd_replacetext_case are now replacetext and replacetextEx respectively.
>replacetext and replacetextEx works using strings only; it doesn't convert it into a list and then back into a string.

Fixes some dumb-dumbs in textlist and text2listEx
> "<" where there should be a "<="
> no else case for when the separator is longer than the text (causing empty lists to be returned)
