Blacklist / Whitelist / textarea

[gs58muse]

Hi Nicolas,
some ideas for improvements:

i think it's better to make the "isBlacklisted" Function caseinsensitive. (P01contact_Field.php - Line: 164)
In textareas i want to blacklist e.g. "href=,class=,id= ..." - but in the current version the function works only if the input is exactly like my values in the Backend.

I changed Line 174 + 176 to:
Line 174: $content = array_filter(explode(',', strtolower($cl->content)));
Line 176: $found = preg_match("$avoid", strtolower($this->value));

this works for me.

I also added the maxlength-attribute to "<textarea id= ..>" in Line 214.
$html .= '<textarea id="' . $id . '" rows="10" maxlength="3000" ';
So I prevent too long inputs (possibly from the clipboard)

Greetings
Gerhard
