Update to support TIGER 2013

[robe]

According to news on TIGER site, they will be producing the 2013 files this month (August 2013).

Hope to jump on it as soon as it is available. Hopefully won't require too much (if any changing at all) of our loader scripts.

I'm also going to flatter the extras folder. Right now extras tiger structure looks like

extras\tiger_geocoder\tiger_2011

This is a misnomer since 2011 and 2012 use the same structure and the logic to load 2012 is in tiger_loader_2012.sql file which is the file included for postgis_tiger_geocoder extension.

Guess have to read this document to make sure no major changes and also to better the approximation of street ranges

e.g compensate that the range is absolute maximum rather than reality.

NAtion script and state scripts seem to be working simply by changing the year in platform. Will close once made this the primary year in extension and tiger scripts after testing a bit more. committed at r11855

I'm going to consider this done. I've tested on MA, DC, and testing now on CA and TX

Hmm I think I had actually shipped this with 2.1 so doesn't belong as a 2.2 item.
