This PR enhances consolidateunspent. It implements two new parameters which correspond to two new features:

  1. [sweep all addresses], which is an optional boolean that defaults to false. If set true, then all inputs that belong to the walletholder (ISMINE) are selected as candidates for the consolidation, not just inputs from the specified address. The output of the consolidation will go to the specified address in this case.
  2. [sweep change], which is an optional boolean that defaults to false. If set true then inputs that have change addresses that were change of an input address that corresponds to the specified consolidation address are also included in the consolidation. If the [sweep all addresses] is set true, then the setting of this is irrelevant and is ignored (i.e. change sweep is implied when [sweep all addresses] is set).

I also corrected the fee calculations, as I discovered a slight error was causing rejects in certain corner cases.

This PR also closes #1296 and #638 in a very simple way by adding a "reset" button to reset the inputs.

This commit implements two new features for consolidateunspent:

1. The ability to consolidate from all addresses to the specified
address, and

2. The ability to sweep up change in the consolidation.
When advanced coin control is enabled, and via the inputs button
inputs are selected, then those inputs are spent via an underlying
transaction or staking, they become "stuck". This is because
the coinControl object still has the stale COutPuts in it.

A simple reset button has been added that calls SetNull() to
nullify the coinControl object and then updates the coin control
labels. This gets rid of the stuck selected inputs.

This adds a time based expiration to the wallet balance cache
to avoid repeated calls to GetBalance() during periods of rapid
updateTransaction calls due to operations like consolidatunspent
or syncing from zero with a busy wallet.
