Needs to be updated to the 1.3 lex-lambda-sdk

[Quigath]

I tried installing this today but had to make some adjustments to get it to build.
The pom.xml had to be updated:
<groupId>com.github.softwarebymark.lex</groupId> <artifactId>lex-lambda-sdk</artifactId> <version>1.3</version> <scope>compile</scope>
I also had to fix line 61 of HelloBotRequestHandler where I think the correct code should be:
return createDelegateDialogActionResponse(lexRequest.getIntent().getSlots());

Can you please look it over and make any corrections?
