simplifying the env var
for #854 finally updated the sampel data to show how the header fields are automatically detected...
commenting out datumstates
updating local manifest to the current remote urls
Fixes #1162 now you dont have to comment out the servers if you want to use localhost, or if you deploy.

just run scripts/switch_to_develop_locally_offline.sh to develop offline and scripts/switch_to_develop_easy_setup.sh before you commit

this also fixes #1163 so that an appropriate server is selected when the user loads the app.
fixes #1164 turned the warning into a note saying it was possible... dont know why that warning was there in the first place
