Update india_356_2.cif

There are additional changes needed, as well as additions to india_update() to make sure existing sites get these changes.

Here are the the ISO 3166-2 updates to IN since india_356_2.cif was last modified:

2014-10-30 	Add 1 state IN-TG; change spelling of IN-OR; update List Source and Code Source
2011-12-13 	Addition of local generic administrative terms, update of the official languages according to ISO 3166-2, addition of a comment and source list update.

The attached patch makes these modifications and adds the update functionality.

Please review the entire CIF for accuracy, especially:
1) Subdivision names
2) Subdivision codes
3) Address format (very important!)

Also, please test the patch by applying it then using the update link at admin/store/settings/countries to update your site's country information. Note, you will have to revert any changes you've made to your copy of india_356_2.cif before you apply the patch.

Sorry, the patch in #3 was for 6.x-2.x. Here's the correct patch for 7.x-3.x

@visabhishek, can you test this?

I think there is something wrong with the country update code.

I installed india_356_2.cif from the 7.x-3.x repo. Then I patched with #6 and clicked "update" in the UI. I now have Telangana added, but I also have two duplicates: Lakshadweep and Puducherry are listed twice in the database. It seems like update 2 ran again, even though it didn't need to? The version numbers were correct before and after the update, however.

This patch fixes the update logic. This would only affect countries with two updates and that add new zones in update 2, which is probably why it wasn't spotted before - this only seems to apply to Italy and New Zealand.

Committed fix for 7.x-3.x, here's a re-roll of #3 for 6.x-2.x including the update logic fix from #10.

Fix committed to 8.x-4.x

DrupalCI is testing the D6 patch against D7.

Committed #12 to 6.x-2.x
