/**
* The KoScriptManagerAddTypeWidget widget is the first page within
* the \a KoScriptManagerAddWizard dialog that displays the different
* ways to add resources.
*
* There exist 4 ways to add resources:
*     \li Add script file.
*         The next widget will be a \a KoScriptManagerAddFileWidget
*         widget to choose a script file and then the
*         \a KoScriptManagerAddScriptWidget widget is displayed to
*         tweak the settings for the new \a Action instance before
*         it's added.
*     \li Add collection folder.
*         The next widget will be a \a KoScriptManagerAddCollectionWidget
*         widget to define the settings for the new \a ActionCollection
*         instance before it's added.
*     \li Install script package file.
*         Not done yet. The idea is to allow to add script packages which
*         are simple tarballs + a scripts.rc file that contains the
*         settings for the new \a Action and/or \a ActionCollection
*         instances that should be added.
*     \li Install online script package.
*         Not done yet. Same as the "Install script package file" above
*         except that GetHotNewStuff is used to fetch the script package
*         from an online address.
