Hi
In this patch I have added support for Gurmukhi Addak, Yakash, Udaat etc to
improve its composition rules.
I have also added the word "Gurmukhi" to the doc-string of punjabi-itrans
and punjabi-inscript so that they could be more easily found.

Finally I have also added support for chess symbols.

Please review the patch, it will be attached in the next mail.
Thanks.
