Now pushing all changes related to PC/SC support
Add pkg-config checks for OpenSSL and CppUnit
Updated card test with reports that report all values for failure cases. Also reports min. and max. bit sizes of all parameters in success and failure cases.
Added simple key generation utility
Merge branch 'master' of github.com:credentials/silvia
Fixed issue #3 by adding unistd.h as include
Merge branch 'master' of github.com:credentials/silvia
Fixed small memory leak in key generation application
Corrected an off-by-one error, with n attributes n+1 bases are needed
Merge branch 'master' of github.com:credentials/silvia
Merge branch 'master' into cmake
Fixed the following issues:

Issue #1: make building tests optional; --without-tests is now supported as an argument to ./configure

Issue #2: Cross-compile fails on configure OpenSSL check; pkg-config solution fixed and merged

Issue #5: No ABI version numbering; spurious -avoid-version option to libtool removed

Also: made building with PC/SC lite optional; --without-pcsc is now supported as an argument to ./configure
Fixed issue #4
Added XML parsing and verifier specification class
Added a verifier class for IRMA cards. This verifier class will generate a list of commands to send to the card to create a credential proof and accepts a list of return values from the card that it will use to verify the proof.
Added a simple verifier command-line utility
Fixed bug in attribute release specification and added support for displaying revealed attributes to verifier cmd-line app
Now builds with PC/SC support on Mac OS X using system PC/SC framework (requires XCode)
Small fixes, add keygen support
Merge branch 'master' into cmake
