Move patch files into a 'Patches' directory in each package

Follow the instructions in 'Scripts/HowtoPopulatePackages.rst' to
migrate current KIDS patches to new directory structure.

First remove the old empty directories:

 find . -mindepth 2 -path "*/Patches" -prune -o -path "*/Uncategorized" -prune -o -type d -print0 | xargs -0 rmdir

The command will warn about files still in the way.  These were placed
by hand in earlier commits, so move them by hand:

 git mv "NHIN 1.0"/* "Patches/NHIN 1.0/" &&
 git mv "Patient Assessment Documentation/NUPA 1.0"/* "Patient Assessment Documentation/Patches/NUPA 1.0/" &&
 git mv "Inpatient Medications/PSJ_5.0_261"/* "Inpatient Medications/Patches/PSJ_5.0_261/" &&
 git mv Imaging/MAG_3.0_121/* Imaging/Patches/MAG_3.0_121/ &&
 git mv "Foundations/XOBU 1.6"/* "Foundations/Patches/XOBU 1.6/" &&
 git mv "Lexicon Utility/LEX_2.0_76"/* "Lexicon Utility/Patches/LEX_2.0_76/" &&
 git mv "Lexicon Utility/LEX_2.0_74"/* "Lexicon Utility/Patches/LEX_2.0_74/" &&
 git mv "Lexicon Utility/LEX_2.0_79"/* "Lexicon Utility/Patches/LEX_2.0_79/" &&
 git mv "Lexicon Utility/LEX_2.0_78"/* "Lexicon Utility/Patches/LEX_2.0_78/" &&
 git mv "Lexicon Utility/LEX_2.0_82"/* "Lexicon Utility/Patches/LEX_2.0_82/" &&
 git mv "Lexicon Utility/LEX_2.0_84"/* "Lexicon Utility/Patches/LEX_2.0_84/" &&
 git mv "Lexicon Utility/LEX_2.0_83"/* "Lexicon Utility/Patches/LEX_2.0_83/" &&
 git mv "Lexicon Utility/LEX_2.0_77"/* "Lexicon Utility/Patches/LEX_2.0_77/" &&
 git mv "Kernel/XU_8.0_599"/* "Kernel/Patches/XU_8.0_599/"

Finally repeat the above rmdir command line to verify no files remain in
the way.
