EditFeature_Drag and EditFeature_Copy - new widgets

[adube]

Create a new editing widget for dragging and copy/paste purpose.

Featuring :

• a 'copy' boolean option :
  • true : on select, should make a copy of the feature in INSERT mode
  • false : should select it in UPDATE mode
• use of an OpenLayers.Control.ModifyFeature with dragging option enabled
• on drag complete, open feature_panel OR simple "done ?" popup to delegate the editing to an external editfeature_update widget
• allow positioning of copies created with an offset (in pixels)

[adube]

The widget should be able to "create" and "update", but for simplicity purpose its action could be "create" only.

[adube]

Its PGSQLMapContextConfig resource option required will be 'editable'.

[adube]

The 'copy' option would add lots of complexity in the code and in the config as well, and since both tasks could be easily handled separately, it would be best to have 2 widgets instead of one : editfeature_drag and editfeature_copy.
