package and download not named for theme (was 'generated zip file not named for theme')

[joeldcanfield]

The package name throughout all files is 'spinhead', one of the other form fields, rather than 'diyogi', the theme name I chose.

The downloaded zip file of the theme was named for one of the other fields, not the theme.

It's confusing, and combined with the unexpected automatic download when a user clicks the Generate My Theme button, could easily result in someone never realizing the theme had been successfully generated since no file bearing the theme name is created.
