Add Instructions for Build Script
Merge pull request #3 from mmcfarland/topic/basic-build-script

Build Script
Allow script to build multi-regions via conf

Add a conf file option that will read a line delimited list of
github Org/Repo to build installers from.  It is intended that
cr.conf will eventually enumerate all Coastal Resilience Network
regions which can all be updated at the same time.
Add NSI installer scripts

These scripts are necessary to compile installer.nsi files
