Port StartupAction>>execute from Pharo 2.0, which seems to be working.

Manually tested in 1.4 with:
        | item1 item2 |
        item1 := StartupAction name: 'Open Help' code: 'Workspace openContents: ''Here is just an example of how to use the StartupLoader.
I should only be displayed once.
       
 You can also see StartupLoader class>>#example'' label: ''Help''' runOnce: true.
        item2 := StartupAction name: 'Open Workspace' code:  [ Workspace openContents: 'I should be displayed each time' ].
" StartupLoader default addAtStartup: {item1. item2}."
        FileLocator imageDirectory ensureDirectory / StartupLoader default startupScriptName fileStreamDo: [ :str |
                str nextPutAll: (StartupLoader default buildStreamFor: {item1. item2}) ].
       
        StartupLoader default loadStartupScript.
        StartupLoader default loadStartupScript.
