xtend thuban with a locator tool.

Collect positions of mouse clicks (in map coordinates) in a text control. 

The tool was implemented in the need to collect some coordinates for some
work (outside Thuban). The status bar display of the coordinates is quite 
transient (each mouse movement changes it) and cannot be copied. The tool let 
one simply collect the coordinates needed and copy them in one block later.
