This commit does following changes to time variables in net_processing.h:
- Used {} initialization.
- Uses universal initializer auto.
- Uses chrono::literals
The reason for these changes is to make code simpler, and easier to
understand and rationalize.
The WalletControllerActivity progress dialog had title of "Bitcoin-Qt".
The window title for opening wallet window should be "Open Wallet",
for creating wallet window should be "Create Wallet", and for the window
that is displayed when wallets are being loaded at startup should be
"Load Wallets". This PR fixes that.
