Data usage performance, bugfixes.

Optimize launch times by removing unneeded extra work, including reloading data and tightening chart invalidation. Fix invalidation storm when sweeps overlap. Move chart history into loader instead of blocking main thread. Disable "Split 4G" mode until telephony support is ready, and combine any existing split policies. Async loading of application details. Remove alpha transitions to speed up on some hardware. Hide menus in detail mode. Delay kicking off force-poll. Fix inset padding on large devices.
