added PAL60 specification. even though it isn't a real specification it
is more convenient and provides better user feedback
moved FrameInfo into frameinfo package, now called Current as in
frameinfo.Current
clarified storage of requested specification by the television:
how the television is probed for the specification has changed, in
particular the current spec is retreived via the GetFrameInfo()

also existed a GetSpecID() which was uncessary
GetReqSpecID() and GetCreationSpecID() removed, replaced with
GetResetSpecID() and IsAutoSpec()
simplified SetSpec(). removed the force argument
removed reset option for vcs.AttachCartridge()
checks that linters exist before proceeding. project URL for each linter
in the Makefile comments
only go-errorlint and unconvert used at the moment
fixed all lint errors for the added linters

environment.Environment type satisifies the Permission interface
