Fixes issue #71
Created by: GpanosXP
Input validator isAddress(address)
now checks isString(address)
.
Also, regex.test(<something>) && isString(<something>)
,
swapped to isString(<something>) && regex.test(<something>)
,
for correct short-circuit evaluation, although I don't thing the isString is needed at all there,
(regex.test does that internally).
