Suppress excessive notifications / confirmations for specified (trusted) apps

[i3v]

KeeAgent is currently (version 0.13.8.0) able to "Always require confirmation when client program requests to use key" and "Show notification whenever key is used by a client program". Both options are useful in general (at least for paranoiacs), but could be annoying for well-known and repetitive scenarios.

• For example, it is possible to setup KeePass to periodically sync its database with a remote ssh server using IOProtocolExt. However, each sync results in ~6 individual Windows notifications (because IOProtocolExt re-establishes the connection several times).
• Another example is WinSCP multi-threaded file copying - with 9 worker threads it generates 9 separate notifications.

It would be great to have some "noise suppression filter" (a list of known apps, configured in KeeAgent settings) for the said two options:

1. an option to "always trust" some executable (e.g. KeePass itself) - don't ask for confirmations, don't show notifications.
2. an option to "ask once" and/or "notify once" (e.g. for WinSCP) - after WinSCP received an "access to a specific key" (e.g. established a first connection to some SSH server), it makes little sense to ask/notify about new connections of the same process to the same server.

Just so there's something saying why this can't happen in case someone else looks: The ssh-agent protocol itself has no security at all, and in fact has no way to even say what application is requesting a key.

The relevant parts of the protocol are here: Listing the keys, and then performing a private key operation.
