Support autofilling wireless network passwords in Android

[luckyrat]

Android only tells us that the password is for "com.android.settings", which is such a vague identifier that we have to ignore the autofill request entirely.

We could try removing that application ID from the permanent exclusion list and adding it to a new list of vague IDs. Applications on that vague list could be autofilled by a Kee Vault user but only temporarily - they will have to search for the desired password every time rather than us remember their preference in future like we do for most apps and websites.
