Code editor: jumplist recent files

[icewolfz]

Add support for jump list recent file list for code editor, this probably requires a single instant and some way to only have 1 version of editor only open which right now is not supported as it allows as many editors open as single instant is client only side, no real way to handle that with out some type of custom IPC i be leave

Another issue is the recent list sends the file name as a command line argument, granted not sure how electron builder sets file associates so this may be possible to prepend the -eo flag to open in code editor or -e for current active client

On windows this requires registering the program for the supported file types, electron builder has a file associate option, should just have to list all the file types and in theory it should work

File types: .c, .h, .o, .design, .map, .cfg, .txt
