'Licensed to' names are cut in length by 1 byte

[dchest]

Currently EllipticLicense generates signatures for message - 1 byte, that is, if given 'John Doe' it will generate key for 'John Do'. If fixed, it will render the generated keys incompatible with previous versions.

Possibly, will introduce a flag for this.

The bug is in:

SHA1((unsigned char *)name, strlen(name)-1, hash);

Must be:

SHA1((unsigned char *)name, strlen(name), hash);

This would also fix inability to generate keys for names of only 1 byte.

Note to self: also fix + (NSData *)el_dataWithStringNoNull:(NSString *)string;, etc.
