v0.8.0

• Breaking options change: unicodeArray option has been renamed to stringArray.
• Breaking options change: unicodeArrayThreshold option has been renamed to stringArrayThreshold.

• Breaking change: option wrapUnicodeArrayCalls was removed and now all calls to stringArray are always wrapped by special wrapper function.
• New option unicodeEscapeSequence allows to enable/disable strings conversion to unicode escape sequence.
• New option domainLock locks the obfuscated source code so it only runs on specific domains and/or sub-domains.
