Add long filename support if DOS version is 7.0 or higher.

[nl255]

I have noticed that even after running "ver set 7.0" there is no long filename support either with the built in dir command or software like pedit that supposedly has long filename support.

The way DOSBox is built from the ground up is based on 8.3 filenames. This would not be an easy task to add and unless original DOSBox (which this core is based on) would implement this, there is slim chance DOSBox Pure would ever get support for long filenames. The ZIP mounting feature of DOSBox Pure is also built with only 8.3 style filenames in mind.

I think it's possible to mount a hard disk image and run a full OS (like Windows 95) in DOSBox (even in this core) which will enable use of long filenames. That is possible because it's accessing a disk image directly instead of going through DOSBox's file system emulation.

Are there any DOS games that need DOS 7 with long filename support?
