Code/compile fixes

[quantaf1re]

Changed:

• Spelling
• Mentioning that nothing is supposed to be cloned
• Saying to create files instead of open them when they don't exist
• Added the comma so this can compile:

    var app = &helloChainApp{
        appStarter,
    }

• Moving the make.md file to near the end because it requires that the cli is built
• Corrected file path to x/greeter/client/cli/query.go in client.md

Love the PR thank you!!!

I'm curious to hear @hschoenburg 's thoughts about the re-ordering of the tutorial though. I think he had that order in mind to show what a completely basic chain could do before showing what extra functionality could add.

Might make sense to switch it up, but if so we should keep an eye out for continuity errors like here:

... Now lets add some functionality of our own making to see how flexible
the Cosmos SDK can be.

Ok, I added another PR without the restructuring

Sorry, I meant that I removed the restructuring from this PR and added another PR that includes the restructuring

I do believe this should stay here

The order of the tutorial makes it such that hccli doesn't exist at the point the user make installs this make file - that's why I originally reordered the files, which is now in #185
