Add ability to move a geo object on the AOI map

Add ability to move a geo object on the AOI map.
Example url type: /geoq/aois/work/7633

When you have photos (or other object), if the obj has the wrong lat & long, we want to be able to move that obj to more appropriate area & track the original lat & long, along with the newly assigned lat & long.

Add a level confidence to the movement --- Low, medium, high.

Same concept documented here: jaycrossler/geoq-django#19 (comment)
