Let the user add other items to quick links

After starting to use the RC 1 version for actual writing, it is immediately clear that the quick links feature is quite useful. Especially for those of us who prefer to navigate by keyboard.

The quick links feature in the project tree is currently populated with root folders. This feature could be extended to allow the user to add any item to the list, and the option to remove items, including root folders.

This means:

• The quick links list needs to be saved in the project file.
• Root folders should be added automatically when they are first created.
• A function needs to be added to the project class that populates the list with initial values for when a project is created.
• This function should also be triggered the first time a project is opened with the version where this feature was implemented. Since each project file is stamped with the hex version of the app when it is saved, this should be easy enough to detect.
