Do not run zxcvbn on long passwords

[ghost]

As I know from personal experience, long passwords result in the web-page hanging due to strength estimation.

I would consider placing this limit as 64 chars instead, as you can get pretty insecure passwords by combining 3 dictionary words that are still longer than 24 chars.

According to this issue and a few related issues, the issues only start to appear in the order of 256+ chars, so this limit could be placed around 128 safely, while still ensuring the security of passwords is properly checked.

Changed to 128
