Manual sorting of the channel/history lists

[jamaljsr]

Users should have the ability to manually sort the channel and history lists.

LiT currently sorts channels by the status of the channel balances, based on the Channel Balance Mode configured in the settings. Occasionally, you may want to sort by the other columns in the list.

The Loop history list is currently sorted by the swap's UpdatedDate descending. This also should allow manually changing the sort order.
