Tabs in whitespace of multiline txt record

[pjjonesnz]

If there are tabs at the beginning of the second (or subsequent) lines in a multi line TXT record, the tokenizer only returns the first line of text. It correctly ignores space and newline, but currently doesn't ignore tab.

While this may not be too widespread, the functions that DirectAdmin (server management software) uses to create TXT records inserts tabs at the beginning of the second (and subsequent) lines of a multi line TXT record, and as DirectAdmin is widely used it would be nice to be able to support this.

I've created a fix and a pull request for this: #23

I appreciate your fantastic script - thanks!
