Use a date value other than (or in addition to) inode mod date ("Create date")

The only date value used by filebrowser at this time is "Create date" which (on Linux, at least) seems to be the non-modifiable inode mod date from the filesystem. As this is not modifiable without major sysadmin effort and isn't settable when files are FTP'ed or copied into the filesystem, this ends up always being the exact date the copy of the file was created, which can cause troubles for migrated content where you want to maintain the historical dates.

Granted, linux filesystem date management is insufficient here, in general, but one could at least provide for the use of a "last update" time, which can be preserved by most FTP and copy functions. Adding this as an option for display and sorting would go a long way toward helping those of us doing file migrations.
