All versions of FitIt for FitBit®

****** IMPORTANT ******** Please uninstall and reinstall the FitItPro. Because of the changes done by the Fitbit server, the application needs to be re-authenticated. ****************************** Fixes: - Fitbit authentication url change - Fitbit requirement to use OAuth2.0 authentication - Improved and easier setup. No longer needed to copy/paste the PIN - more devices to support (Charge, Alta, ChargeHR, Blaze and Surge)
