Misc cleanup; 2013 and 2014 processed app/grant files

Various depricated files have been moved to the `miscFiles/` directory.

Processed applications for 2013 and 2014 have been placed in the `processedApps/` directory.  Similarly, processed grants have been placed in the `processedGrants/` directory.  In each case, there are per-year combined `.csv` files.

The `ptoids` column (and associated `processFile.rb` code) has been removed.

A new `combine_csvs.rb` script has been added to automate the concatination of `csv` files.
