Description requirement for flagging developments

[alexgbob]

Describe the feature. What should a user be able to do?
Require users who want to flag a development to add a description for why they are flagging

Why do we need this feature?
At this point there is no clear way to know why someone flagged a development and trying to figure out why can be time consuming.

Alternatives
There could also be a multiple choice list of options for why the user is flagging the development
