remove /dexcomserialport.json, /diypsconfig.json and /mongoconfig.json configs; move their settings to chrome.storage.local; new setting for mg/dl vs mmo/l; make reports aware of mmo/L option
check for bgs less often (to give download all more time to run)
remove chromeext.php because diyps now pulls from mongolab instead of needing pushed to
bumped app version
version bump & rename to chromadex for appearance in store
don't blow up when config not set
