Configuration scheme:
shellexec.NN shcmd:title:name:flags
@shcmd is the command executed by the shell
formating directives are allowed, see
format_shell_command function
@title is the title of command displayed in UI
@name used for referencing command, for example in hotkeys
configuration
@flags comma-separated of command flags, allowed flags are:
single - command allowed only for single track
local - command allowed only for local files
remote - command allowed only for non-local files
disabled - ignore command
