Do not start Smart Card Reader android app when a card is started

[sonicdebris]

More of UX change proposal then a bug:

Expected behaviour

When using another app that reads NFC cards (eg: CieID), putting the card close to the phone will cause Smart Card Reader to be started. This interferes with the usage of such other apps.

Actual behaviour

Smart Card Reader should read NFC cards only while it's open.

Notes

I think it's a matter of just removing the android.nfc.action.TECH_DISCOVERED intent filter. Then it might be to set this dynamically, with an option in the settings.

smart card reader app offers to handle the nfc card. if you have multiple apps installed that could handle the card, you will see a dialog from your os with options what app to select, even allowing you to select some default app. this mechanism is entirely built into android os and doesn't interfere with any app workflow.
