Use inlined FNV1a hash for String ...and do not use __symbolHash(). Although currently the VM also uses FNV1a hash for Symbols, the __symbolHash() does not handle properly character with codepoint 0 (because '\0' is used as a string terminator). This causes problems with Unicode16/32Strigs whose version of FNV1a hash is using object size from header to determine string's end. Added Symbol>>hash that actually *uses* the __symbolHash() to make sure it's hash is the the same as used bu the VM. Symbols with zeroes are rare and there's no Unicode16/32Symbol. This commit fixes issue #65.
