[Feature Request] Relative file paths when adding files from the ZDL folder

[madTrance]

If I have my 'mods' folder inside the 'ZDL' folder, when dragging mods into the 'External 'Files' window of ZDL, could there be an option to create a file path that starts from ZDL.exe's containing folder rather than from the drive letter? So instead of "[C:/Games/Doom/ZDL/Wads/Scythe.wad]" it would be "[Wads/Scythe.wad]", beginning the file search inside /ZDL/ instead of C:/. It would hopefully allow for having a portable "all-in-one" folder that can be moved around without breaking profiles.
