New in ISPConfig development and have some questions

[karailiev]

Hello all!
I'm new in the development team and have few questions.
I've assigned to myself a ticket about password strength indicator and I have it working. It's about 100 lines javascript and I'm wondering where to put it.
When I add it to interface\web\js\scrigo.js it's working fine, but I want to ask if this is the right place.
I also have to create new label "Password strength", so I added it to interface\web\client\lib\lang\en_client.lng
Should I edit other languages' files (de/it/fr/nl) or should I somehow inform the users who maintain them?
