Add meeting entry finding information to Location model.

[destos]

May need to have a better label than "entry". Mainly how to find where you need to walk once parked to get to the meeting.

This feature/field would allow you to enter a little descriptive text related to how to find the entrance to the meeting place. You could also add directions on how to find the meeting inside whatever place it resides.

You would have to:

• Add a new text field to the Locations model.
• Add that information to whatever template the location information is output in. ( where relevant )
• Add migrations for the model change.
• Add the field to the Django admin.
