Update 'publicly_available' and 'status' default values.

[philip-cline]

Description

Update the default values of status and publicly available feeds to be "Approved" and "Yes", respectively. This was just a simple change to the generateProps function in editor/util/gtfs.js to assign a value of 1 to publicly_visible, and 2 to status. This should better conform to user expectations for a new route.

resolves #589
