#116 ebcdic id_rsa and id_rsa.pub is not working

[Saiyin Leung]

It appears RSA key has to be ascii or otherwise doesnt work..... I have id_rsa and id_rsa.pub as EBCDIC .. but looks like JSch reads the files using FileInputStream to load the files in to byte arrays.
In order to make it work in ebcdic systems, I did two things:

1. convert id_rsa and id_rsa.pub to ascii
2. modify IdentityFile.getAlgName() to use [new String(kpair.getKeyTypeName(), "UTF-8")] , to override the default ebcdic encoding in my system.
