Do not use LastIcon and LastBinFile if those files do not exist
Add new directives, see details:

;@Ahk2Exe-SetCompanyName txt
    Obvious
;@Ahk2Exe-SetMainIcon [icoFile]

    is not specified, the icon is left as the default AHK icon.
;@Ahk2Exe-PostExec command
    Executes a command after compilation.
;@Ahk2Exe-UseSeparateTrayIcon
    Makes the AHK runtime continue to use the separate tray icon
    resource as in compiled scripts with no custom icon.
;@Ahk2Exe-SetConsoleSubsys
    Changes the executable subsystem to Console mode.
