Use stored user's repositories for each filter/sort is "all" are loaded
Use stored user's stars for each sort is "all" are loaded

Update is very long, maybe we can reuse items in the list instead of
removing then and recreate new ones ?
Use pure dom to update lists
Toggle class instead of show/hide in jquery (lot faster)
Correct a css default in the main account/repo home block
Remove templates from dom when loaded
Keep only needed fields from fetched data
Save fields used for sorting
