Improve the user interactions over plot: zooming and range dragging.

Browse Source 
The rectangle selection is no longer possible. Control+click can be used
for selecting a range of items.

This allows more freedom for performing customisations as requested in
issue "Change axis limits #838".

The "Load all data" button tool-tip and icon have been readjusted so they
hint the additional use pattern of resetting the plot to the original
zoom and range limits.

New and more appropriate icon for the "Save Plot" button. Icon from the
Silk set from famfamfam.com.
