Better naming for TXT files

[irigone]

Currently, txt files have the model ID as their name. Maybe it's better if they have the keyboard name in the file name, too? Some people have 2 keyboards, having files with distinguishable name such as "655491117GK61 RGB.txt" would be far better in my opinion.

To not be a breaking change this would need to be optional i.e. support both 655491117.txt and 655491117-GK61 RGB.txt. Code like the following would need to be changed to check multiple paths:

GK6X/GK6X/Program.cs

Line 461 in 7c8b9ce

UserDataFile userData = UserDataFile.Load(device.State, GetUserDataFile(device));

I forked a copy to play with it. I added command line args for gui mode and a filename option and prefix. This way I can play with multiple files for the same device at the same time. It was easier to do rollbacks this way. This seems to work pretty well.
