Minor fix to ensure views/controllers are generated into the view directory

Hi, This is just a minor fix to ensure views/controllers are generated into the view directory. I thought about allowing the user to specify the directory (as you had it) but it seems more like convention to use "view" as the directory name. There was a couple of other spelling fixes I added. If you'd like to merge this in, then at least any user will have a working app immediately after running yo sapui5.
I'll look at adding in XML view generation next. Just wondering - it looks like you've started adding some code to use the Component model - I might finish that off first unless you are working on it now?
Regards... Jason.
