tools: add c key to reset ERR counters

Browse source 
Reset the ERR counters when pressing the c key. This only makes the
current pw-top start counting from 0 again, it does not change anything
globally on the server. It's still usefull because you can use it to
let it count the number of new errors since the keypress.

Clear the ERR counters. This does *not* clear the counters globally,
it will only reset the counters in this instance of *pw-top*.
