Display of files in folders does not follow alphanumberic conventions

[Don Presant]

If you try to reorder files in an online folder by renaming them, files starting a,b,c...come before files starting 1,2,3...this does not follow alphanumeric conventions.

Display of files in folders does not follow alphanumberic conventions
(Bug 1180775)

The sort function adds a 0 in front of folders and a 1 in front of file
names to display folders first. So, the sort order is really by numbers,
and if a file has a number in the beginning, it ends up at the end of
the list.

I am separating the initial number and the file name with an 'a'
character, so that the sort order is - first folders, then files, and
all sorted by title.
