New function to modify the maximum call stack size limit about pyv8 HOT 4 CLOSED

BTW, I cannot change the Type-Defect, but I consider this as a new 
feature/function request, because I have already taken a look at other defect 
issues related to this error.

I will woking on it later :)

Please use JSEngine.setStackLimit with SVN trunk code after r574

https://code.google.com/p/pyv8/source/browse/trunk/PyV8.py#2241

Thanks a lot for adding the function! :) You can add peepdf 
(http://eternal-todo.com/tools/peepdf-pdf-analysis-tool) as another project 
using PyV8 ;)
