(DP45) No Index Topics

This mod counting all words (at least two chars per word) belonging to a topic.

When the topic is posted:

• if more than XXX words: INDEX
• if less than XXX words: NOINDEX

After it was posted, if the topic was marked NOINDEX (and only if, it doesn't count again for already INDEX topics), it counts again when somebody replies to it, then same thing:

• if more than XXX words: INDEX
• if not, no change

 Working fine for exists topics too.
