Resolved incorrect git sumodule path for funnel

Hi there,

List of changes in my pull request-

* Updated the .gitmodules resolving outdated url reference for the 'funnel' submodule.
* Updated, subproject commit to point to the latest commit in the funnel/master branch on hasgeek.
* Further added a trivial filter to .gitignore.

Question (separate):
Shouldn't the repository name be updated? **pyconindia2012** is confusing, it also being used for Pycon India 2013.
