Fast compiling of DPdash

Non-minifying significantly increases speed of npm run build. Previously, it took 10 minutes. Now it takes only 1 minute! The developer branch has been set up to use non-minified *js files. Compile fast as follows:

cd /sw/apps/dpdash/

singularity/quit.sh

rm -f public/js/*js

npm run build

singularity/run.sh
