bwauth should reschedule quicker bandwidth test when bandwidthrate changes?

He apparently switches between 100KB/s and 2MB/s bandwidthrate depending on time of day. His bwauth votes ended up being very skewed:

moria1 says
w Bandwidth=141 Measured=15

ides says
w Bandwidth=141 Measured=26

urras says
w Bandwidth=141 Measured=1480

gabelmoo says
w Bandwidth=141 Measured=935

It's a shame that we're giving really low numbers to a node that wants to be 2MB/s at some times of day. It probably also means we give high numbers to a slow node if the measurement times are different.
