Implementation for WinBIAP OPACs, a bunch of small things

I implemented WinBIAP OPACs (only search), starting with these three:
http://webopac.winbiap.de/unterfoehring/index.aspx
http://gersthofen.webopac.winbiap.net/gersthofen/
http://webopac.winbiap.de/eschwege/index.aspx
I used the following public domain Base64 implementation instead of the one integrated in Android to make the Unit tests work: http://iharder.sourceforge.net/current/java/base64/
I also created a Python script which will make adding all the WinBIAP libraries from the list easier.

Other random things:
- Added Library Wetzlar (Bibliotheca)
- Maybe fixed strange account bug in Adis where the reservation table has one column less
- Added HTTPS URL and right charset for Wiesbaden HLB
