[network-manager-applet/lr/pkcs11: 14/15] libnma: add the PKCS#11 capable certificate chooser



commit 967e38b6c4fd2d87bcf4e4f55901a0859e5f52bf
Author: Lubomir Rintel <lkundrak v3 sk>

    libnma: add the PKCS#11 capable certificate chooser
    
    Default to it unless Gcr support is unavailable or an application
    indicateas it only supports certificates in plain files.
    
    This one is libnma only. The libnm-gtk can still utilize the
    NMAFileCertChooser. Since libnm-glib doesn't support PKCS#11 tokens it
    wouldn't make too much sense anyway.
