Removed key size check (for encrypted wallet).
Keys are usually 279 bytes long, but I got one of size 278 in my wallet. Eventually we should move towards Bitcoin approach of storing 32-byte secret only (and derive priv/pub key from it).
Small refactoring - moved a function from keystore.h to .cpp.
Fixed deadlock when calling name_firstupdate from GUI RPC console. Updated version to 3.57
