Limit download progress percentage to range 0-100

[robho]

For nobil the percentage reaches 101. I haven't figured out why nobil's data is out of sync.

When querying nobil for the total number of chargers we get:

Norway: 4957
Sweden: 9108
------------
       14065

.. but the data dump we download has:

Norway: 5168
Sweden: 9059
------------
       14227

---

Could be fixed in the nobil data source instead if that's more appropriate..
