Ordering of data structures

[tardypad]

Currently the groups and data structures are ordered in the apidoc in the order they were included in the apib file.
While I think this is fine for the groups part, since we generally want to order them manually for some diverse reasons, it is a bit inconvenient for the data structures when we want to reach a particular one.
I think it would make sense to order them alphabetically by their name.

Don't think this would be a real benefit over manually sorting them. They're handled in the way they are in the APIB and nothing more.

I could make a button to sort them but I personally don't see the benefit @tardypad

Decided on making it a compile flag
