Rename the "upload_limit" variable to "simultaneous_upload_limit" for

clarity, since it only limits concurrency not the number of actual uploads.

Move the default-setting code into the upgrader so that we avoid
creating the variable as a side-effect of the view (personal
preference to avoid side-effect code since it's led to problems in the
past).
