LibGUI+FileManager: Merge GDirectoryModel into GFileSystemModel
We used to have two different models for displaying file system contents: the FileManager-grade table-like directory model, which exposed rich data (such as file icons with integrated image previews) about contents of a single directory, and the tree-like GFileSystemModel, which only exposed a tree of file names with very basic info about them. This commit unifies the two. The new GFileSystemModel can be used both as a tree-like and as a table-like model, or in fact in both ways simultaneously. It exposes rich data about a file system subtree rooted at the given root. The users of the two previous models are all ported to use this new model.
