Prepare to organize April/May/June 2013 FOIA patch files

Update Scripts/KIDSAssociatedFilesMapping.py to place files with
patches.  Place LEX_2_90.GBLs with patch "LEX*2*90".  Place
"PREC - PHARMACY ENTERPRISE CUSTOMIZATION SYSTEM RELEASE.txt"
with patch "PREC*2.2*1"

Files in the "June 2013/CPRS VERSION 29 - ALSO IN INDIVIDUAL APPS"
directory all exist in the parent directory too, and are identical.
Remove them.  Also remove the "CPRS 29 Source Code Note.txt" note
about non-availability of the FOIA version of the source code.

Remove "RMIM-1_SEQ-6_PAT-6.TXT" because we already have an identical
copy in "Packages/Functional Independence/Patches/RMIM_1.0_6".
