Add a file type

[wux4an]

Not adding the file type before any word, in my opinion is a somewhat necessary implementation to have more space and would make it look better.

os.ReadDir golang syscall that we use to list files in filePanel doesn't provides FileType info.
Although we could use lexers.Match(<file>).Config().Name from "github.com/alecthomas/chroma/v2/lexers". We already use that package while previewing files.
Or we could use file or exiftool utilities. But that creates a tool dependency in users computer.

I think what they mean is instead of FileName, FileSize, FileModifyDate, and FilePermissions, it should instead be Name, Size, Modify Date, and Permissions.

Woah. Really. How did I misread that !!
