Fix selection of TLS1.1 compatible DIDs and add selection of TLS1.2 compatible DIDs
Select a DID for TLS just if a readable certificate with Client authentication extension is referenced in the DID
Add new SALFileUtils class
Add new data type class DIDCertificate which contains information about a DID and the referenced certificate
Put the certificate data sets in the correct application
Add ACLList AccessRule to the certificate data sets
Save the certificate

- read the certificate
- check whether the certificate contains the client authentication extension
- add missing DSA OIDs
- use the new DIDCertificate type for storing the certificate
- rewrite filterAlwaysReadable method, it is easier with the usage of the new DIDCertificate data type
Use new DIDCertificate data type and SALFileUtils

- remove connectApplication() and getCertificateDataSetName() methods
Disable security check in cardApplicationList and dont filter the app ID in dataSetList
Fix imports after stage rebase and name of DIDCertificate variable
Merge remote-tracking branch 'hm/genericCryptoSignerFinderTLS1.2' into stage
