allView, frequentView: Only create icons when necessary
The views (AllView and FrequentView) build a list of all applications
they contain. BaseView then diffs between what's currently added, and
what needs to be added, and removed.
This approach has a problem though: creating an AppIcon or a FolderIcon
connects to various signals, and we confuse the garbage collector.
When building the list of applications, instead of always creating new
icons, try to use already existing icons first.
