Subject: [PATCH] Include more variables on admin/config page (#6378)

Include the current CustomPath location in the admin section and also
display GITEA_WORK_DIR and/or GITEA_CUSTOM env var if they are set.

Right now there is no easy way to see this information, and if you try
and help most users they won't be able to tell you anything about these
values -- just that their custom template isn't working, files aren't in
the right place, etc... Now you can see all paths and if they were set
by ENV or not.
