API request rate

To combat the large number of pyradmon users sending requests to test_user and test_password I have implemented a rate limit on the radmon API of 10 requests in 30 seconds.
Typically, a user monitoring the map and with 3 logging stations running and sending some experimental requests should not exceed 10 requests per 30s for sure so it seems like a sensible level to set.
The ban after exceeding the request limit is 10 minutes.
Please report if you experience any logging failures on a regular basis with 10 minute interval. The limit may need to be raised, or there may be a problem that needs investigating.

This have been disabled for the time being as anyone browsing to the Stations page would get banned due to the flood of requests for station status and cpm meters, resulting in a connection refused error.
Clearly this will need improving.

Fixed. Rate limits restricted to data submit function only, to combat this specific issue.
