#2 GUI - Display a straight "line of walk" when moving entity

[Fjeld]

When moving an entity the user need some indication of
what his or her limits are. This will eventually lead
to boundary-indicators for single, double and run move
actions, but for now a single line from the spot where
the entity started in his turn, to whereever he is when
moving him around, will suffice.

1. Add a line.
2. Add a trail, where the person has walked, i.e. color
cells he's been walking on.
3. Allow double move action and cell indication of double
move actions.
