major changes, ECTester rewrite, moved to valid package

reader: ECTester, mostly rewritten SimpleAPDU
 - communication with applet now done through simpler
 instructions: allocate, set, generate, ecdh, ecdsa
 - moved to a valid Java package dir cz.crcs.ectester
 - SimpleAPDU: renamed to ECTester
 - CardMngr: seamlessly supports simulation vs real card
 - DirtyLogger: takes a nullable String and creates file
 - ECTester: currently only supports key generation,
 curve testing under way
   - supports external curve setting, example files
   in data package
   - tests can be done through files, to achieve a more
   modular approach
 - Util: static utility class
 - ParamReader: reads curve domain parameters and keys from
 simple csv-like human-readable files with hex strings

applet: ECTesterApplet, rewrite of SimpleECCApplet
 - more granularity in instructions
 - moved complexity over to the reader side
 - ECKeyGenerator: now a class that takes KeyPair as param
 - ECKeyTester: now a class that takes KeyPair as param
 - EC_Consts: removed ecsp curves(now done externally),
 removed unused methods
 - ECTesterApplet: currently only tested instructions are:
 allocate, set, generate

data: contains several curve and pubkey files in format supported
by ParamReader
 - Prime field curves:
   p,a,b,gx,gy,r,k
 - Binary field curves:
   e1,a,b,gx,gy,r,k   or   e1,e2,e3,a,b,gx,gy,r,k
 - Public key:
   wx,wy
 - Private key:
   s
 - Key:
   wx,wy,s
 - all values are hex strings
