[Padma] Reg. Porting Padma to Webkit

Hi Prunthaban,

Padma works by inspecting the font name of all the DOM nodes of the
web page and uses lookup tables to transform text within the DOM nodes
(See onPageLoad function in padma.js[1]). To implement padma in
webkit, we need to start with porting the following modules,
1.  transformation logic.
2.  code pages/lookup tables.

I am interested in contributing for this Padma port. Let me know how
you want to proceed on this.

Thanks
Saravana
