Create Word Count button

[Aung Khant]

Dear Fred and developers,

The word count button will count values in text area by way of -

1. word [Use Regex to determine space]
2. character [ FCKeditor.values.length - length of Regex(whitespace characters) ]
3. line [Use Regex to determine line break characters]
4. paragraph [Use DOM to count p tag]

Thank you so much for your time, consideration and hardwork.
