Allow access to the 128 character filename limit through settings?

[terbo]

In modules\images.py there is a variable max_filename_part_length which sets the maximum file length to 128 characters - can this limit be accessible through the UI settings? Or is there any particular reason why this limit was chosen?

I'm looking into how this would work, but I can see that unless some check is done it could be made too long by users who are unaware of their systems maximum file system limit.
