Program addition: File browser and editor

Browse Source 
- Adds new "File manager" program, that allows you to work with files stored on your device's hard drive.
- File manager can be used to delete/rename/view files. Some files can't be viewed (executable programs), some can be (data files)
- If your device contains NanoPrinter hardware you may print data files.
- You can edit the text files using simplified paper code.
