Add a File snippet

[svenvc]

Often in a narrative on a page we assign some variable to a a file reference to later use that file's contents in further processing.

file := FileLocator imageDirectory / 'myfile.data'

A File snippet would make this explicit and could offer some additional support in setting/locating the file, tracking the file when it moves or resolving special locations like gtResource.

By using the existing support in AbstractFileReference view/editing/parsing/styling are already covered.

The fundamental properties of the File snippet would be the fileReference in File URL form and the binding name.

This is the current state of the File snippet:

Search for the Snippet of type File.

Package Lepiter-Snippet-File, class LeFileSnippet.

This snippet type is rather welcome 👍 . Assuming this would also work for folders right? Would be useful to be able to bind to either (File or Folder). Did some explorations on this a while back on my LepiterBuildingBlocs repo. That pushed the limit of what could be done without creating custom snippet types, but the correct way to do this is with a custom snippet type.
