[Etoys] A few issues and suggestions regarding the etoys image

[Karl]

I noticed that the halomenu for BookMorph still offers sendPagesToServer.

There is no easy way to get a text widget with a scrollbar.

There is inconsistency and unneeded complexity to the ways morphs are 
picked up.
-Some places you have to click and drag to get a morph (Objects tool, 
Supplies flap)
-Some places you get the morph on mouseDown (desktop, tiles in the viewer)
-Some places you get a morph on mouseUp (TestTileButton in 
ScriptEditorMorph, desktop, some tiles in the viewer)

Also sometimes the the hand morph is positioned to the top left corner 
of the script tile morph, sometimes not.
