Attempt to replace 'bcrypt' with 'bcrypt-nodejs'

Hi David,

This is my first pull request ever. Please review carefully. Not sure if I used the correct git hash and format you have requested. This is all new to me (GitHub) and although I researched and read the help, I maybe missing something simple I yet to understand. 

Thank you for your patience. You do not have to use this. Or I can make changes if it is wrong. This is a good learning experience for me, even if you decide to do it yourself.
