CivilTongue: Add poll filtering.

Add filtering to poll data (Title and Options).  
You're making 2 calls to val(), only 1 of which is needed, and neither of which checks for a data type. You assume an array but don't check.

Replace the check by the faster:

```
if (empty($Args['PollOptions']) || !is_array($Args['PollOptions'])) { 
    return
}
```
