Includes changes from PR #1086
Karma tests fail on my laptop
I now have 7 copies of bitcore in my ~/dev directory:

./bitcore
./bitpay/node_modules/bitcore
./bputil/node_modules/bitcore
./bputil/node_modules/bitpay-client/node_modules/bitcore
./copay/node_modules/bitcore
./dashboard/www/lib/bitcore
./node_modules/bitcore

Which one should I use for "bower link" ?
