Case in "Allowed extensions" for File Custom Field

Hello

When you have a File field on a Profile Type, you can define what are the allowed extensions. The problem is they are case sensitive, that is if you define jpg as allowed, if a user tries to upload a file with extensions JPG then it fails...
It certainly should be case insensitive.

We maybe have the same issue for User, Group and Event File fields, User, Group and Event File apps, and for files in conversations...

Thanks
