Add WikiProject banners within {{WikiProject banner shell}}

[siddharthvp]

WikiProject banners should be added within {{WikiProject banner shell}} if it already exists. If it doesn't exist and 3 or more banners are being added, the shell should be added.

This script creates drafts from scratch only, correct? It doesn't edit pre-existing drafts?

Then I wonder why prepareTalkText(initialText) has an initialText param?

The algorithm for fixing WikiProject banners and shells is MUCH more complicated than the algorithm for just adding them. So I want to double check before I decide what approach to take to solve this ticket.

@siddharthvp, any thoughts? Thank you.

@NovemLinguae It only edits pre-existing drafts 🙃 - since this script is for submitting drafts, not creating them.

Note to self when I work on this patch in the future: just copy and adapt the following AFCH code.
