Scripting translation of numerals in check printing plugin

[Shinjo Park]

Hi,

While I was trying to solve the CJK numerals problem in check printing plugin, 
I realized that it is possible to script the translation of numerals. By using 
Transcript [0] it is possible to dynamically modify translations using 
JavaScript, and I think if the numeral system is different from English, 
instead of coding every cases allowing translators to implement it would be a 
good idea. This also addresses Bug 413713 [1].

I made a WIP merge request [2] for the implementation. I am open for any 
comments and suggestions.
