provide value for CommunityID as readable digit-string now

[psytester]

CommunityID is taken now from default value or dataset file in readable digit-string Format.
Benefits:

• internal "NotOnChip" function is now working for DG18
• The value is readable ;-)

Could you check this error: https://travis-ci.org/frankmorgner/vsmartcard/builds/48047723#L4619 , thanks?

Do we have only a chicken-and-egg problem?

TravisCI logfile says:
[.....]
File "virtualsmartcard/tests/CardGenerator_test.py", line 73, in test_readDatagroups
.....
File "virtualsmartcard/CardGenerator.py", line 198, in __generate_nPA
CommunityID_Binary = binascii.unhexlify(CommunityID)
TypeError: Non-hexadecimal digit found

patch-10 is checked and will use the new unit tests in CardGenerator_test.py

patch-11 is a change in text file:
npa-example-data/Example_Dataset_Mueller_Gertrud.txt
--> it contains now an integer value and not longer a hexadecimal string

As long as both patches are not put together it will fail on TravisCI
But in my system the code is working...

I will never apply pull requests without GitHub Client as Webpage produces several commits. one for each file change :-(

closed as patch-10 and patch-12 are merged into patch-11 for a single pull request.
