Added support for extended APDUs, fixed problems with large cmds

- Switched ECTesterApplet to Javacard 2.2.2 which supports Extended
length APDUs (necessary for some Set commands when a large external
curve is sent to the applet)
- The incoming APDU is now copied over to a sufficiently large buffer
before being processed
- Simplified instruction processing logic
- Renamed ECUtil to AppletUtil
- Fixed padding error in nist/P-521
