Make it harder for the user to accidentally hit the openstreetmap attribution link
If the user adds a feature outside of the area of interest, warn them that the feature won't be on the device anymore after syncing.
When the openstreetmap link gets hit, open the link in the browser app instead of the webview
Made it so that if the user doesn't enter credentials, it'll treat the user as anonymous and not include the basic auth headers
Changed the url that we're using to authenticate to a url that can be accessed by any registered user
Removed some dead code
Disabling the syncButton when the user went offline, doesn't seem to be enough to prevent the user from syncing while offline.  Added a check to ensure the user is connected before syncing
Added overlay to prevent clicking when map is being reset.
Make sure that the map doesn't reset when getting a picture that was taken, and don't let the user save a feature until the photo has been added to the feature
Make sure that hitting the add part or add geometry parts more than once won't "reset" the edit
Added Dan's "How to" docs
Make sure the user can't remove geometry parts while in the process of adding a geometry part
