Myproxylogon getcert

Avoid "RSA/ECB/PKCS1Padding is not available from provider Cryptix in OpenJDK 7" bug using MyProxyLogon Lib of http://grid.ncsa.illinois.edu/myproxy/MyProxyLogon/ instead of MyProxy  and using an own implementation to convert private key PKCS#8 in PKCS#1.

This new implementation allows generate a getcert.jar smaller (229,7 kB) than MyProxy version getcert.jar (2,5 MB).

I run succesfully it in openjdk 6/7 and jdk7
