Kill off ShellAppInfo, move into ShellApp This dramatically thins down and sanitizes the application code. The ShellAppSystem changes in a number of ways: * Preferences are special cased more explicitly; they aren't apps, they're shortcuts for an app), and we don't have many of them, so don't need e.g. the optimizations in ShellAppSystem for searching. * get_app() changes to lookup_app() and returns null if an app isn't found. The semantics where it tried to find the .desktop file if we didn't know about it were just broken; I am pretty sure no caller needs this, and if they do we'll fix them. * ShellAppSystem maintains two indexes on apps (by desktop file id and by GMenuTreeEntry), but is no longer in the business of dealing with GMenuTree as far as hierarchy and categories go. That is moved up into js/ui/appDisplay.js. Actually, it flattens both apps and settings. Also, ShellWindowTracker is now the sole reference-owner for window-backed apps. We still do the weird "window:0x1234beef" id for these apps, but a reference is not stored in ShellAppSystem. The js/ui/appDisplay.js code is rewritten, and sucks a lot less. Variable names are clearer: _apps -> _appIcons _filterApp -> _visibleApps _filters -> _categoryBox Similarly for function names. We no longer call (for every app) a recursive lookup in GMenuTree to see if it's in a particular section on every category switch; it's all cached. NOTE - this intentionally reverts the incremental loading code from commit 7813c5b93f6bcde8c4beae286e82bfc472b2b656. It's fast enough here without that. https://bugzilla.gnome.org/show_bug.cgi?id=648149
