Addressed Module: Project.

I use the Description field of a Project to present some general information about the project, the average document length is approximately 150 lines.

In the current version, there is no preview on the [Edit Details] page, so one has to submit the description changes and add clutter to the log or even abuse the "add comments" function of another application.

To make this feature more comfortable and acceptable for other members aswell, I would welcome the same Markup preview functionality as when adding comments to Maniphest tickets or Diff commits.

Steps to reproduce:

Go to the URL below and edit the project description.

https://phabricator.any/project/details/{any}
