Restructure: Fixes #11

[Techassi]

This PR fixes / extends #11 and implements the proposed changes by @muesli.

This also adds one new template helper: toUpper, which uppercases a string.

Any update on this?

[muesli]

Appreciate the effort and it's certainly moving in the right direction, but I don't think we should introduce a generic pkg directory. There ought to be a better name 😄

Also, instead of deleting goodreads.go and replacing it with gr.go, please use git mv to preserve its history. This also makes it easier to review what/if content in these files changed in this PR. If you need help cleaning this up in this branch, I'm happy to help out. Just let me know!

[Techassi]

Thank you for your feedback :)

Maybe a better name for pkg is internal as we don't really want to share the code with other programs.

I will also update the branch to include the history of goodreads.go / gr.go. Is there any particular reason we want to preserve the history of this file other than a better diff? Also are there any other files you want me to preserve the history from?
