Use new 2011 PUF data in Tax-Calculator

[martinholmer]

Merged taxdata pull request 114 and merged taxdata pull request 150 --- both the work of @andersonfrailey --- together create a new puf.csv file and new puf_weights.csv and puf_ratios.csv files. The growfactors.csv file generated by taxdata 114 has been replaced in this pull request by a hand-edited growfactors.csv file that has the same values as on the Tax-Calculator master branch for the years 2012+. (The taxdata version of growfactors.csv is conceptually the same but contains very small differences in the 2012+ growfactor values that generate many failures in unit tests that use CPS input data. The hand-edited version leaves all the CPS results unchanged.)

Using these four new data files, all the CPS-related unit tests continue to pass and, as expected, the PUF-related unit tests produces slightly different results than were generated using the older 2009 PUF data.

This pull request has used the puf.csv file generated by taxdata pull request 150 that has the following characteristics:
