Changed the way the master password hashing works

Switched from Bcrypt to Scrypt for master password hashing
Changed models to use new sizes for hashes and salts, doubled the size of enc_login and enc_passwd for accounts
Created new function to check master password validity
Increased salt sizes for accounts and master passwords
Removed bcrypt from requirements
