 The current selection tool within QGIS can only select features by
 rectangle intersect. This is inadequate for many GIS selection. Attached
 is a patch that adds more selection tools into the core app to aid users
 with more advanced selection problems.

 This patch is partially inspired by Barry Rowlingson's SelectPlus python
 plugin, but adds a single selection tool, provides a toolbar with icons,
 and gives the option to select features either by intersects or contains.

 This patch makes a significant change from the current select by interest
 methodology. Instead by default, each select tool (except for single
 select) selects features by geometric contains. If the user wants to
 select by intersects the ALT modifier key must be pressed at the same
 time. I feel this default behaviour is more in line with other mapping/GIS
 systems.
