fileman.js

Sort of the opposite of the "Offline Files" search, find files copied into
the directory storage paths but not yet added to the filebase, with a
"Add File..." option (and tagging support) along with DELete files option.

Auto-ignore listing files (e.g. FILES.BBS, etc.) when searchign for new
files to add to a directory's filebase.

If an argument is passed to fileman.js, use that as the UIFC mode (for testing
purposes only).

Fix case-sensitive file compares (on *nix OSes) when adding files (now
case-insensitive).

Fix issue with get file paths for files not yet in a filebase (using
FileBath.get_path unnecessarily).

Display virtual paths to files in many place, when available (> SBBS v3.19).
