Allow setting aligned leads as project leads

It would be nice to have a checkbox (similar to “Add Aligned Leads to Project”) that allows the project lead be the same as the aligned lead.
This is useful for projects that are inherently under a lead by role (my regional leadership project is still “led” by the previous RC, for example).

Also, while writing this, I noticed a typo that’s not worth a whole new post:

There’s no need for a colon after a question mark.
