Make pep8 happy
A first ugly attempt to search in remote sources
Search for some sources doesn't return remaining

Also fix some artifacts from rebase
Don't search immideately - wait for 0.5 second
Don't use outdated GObject: use GLib, Luke!
searchbar: more logging
Remove filtering - we're using queries/search now
Do custom queries when tags is selected

For now just query songs for album name works - other queries need update
query: Updated queries for search
window: Overlay search dropdown on stack
view: Enable load on-scroll only if in Icon view

Since the icon view is only used in Albums view, don't connect to draw
events if a list view is being used. This reduces redraws in other
views.
query: Simplify query for playlist songs
