Patch by Iain Merrick <husky@google.com> on 2012-09-18
Reviewed by Ryosuke Niwa.

These methods had "start" and "end" parameters, but this is incorrect.
selectRange() actually takes base and extent (where the user actually
touched), and selectionBounds() returns anchor and focus (base and extent
expanded to account for the selection granularity).

This patch fixes the parameter names, and updates selectRange, its test
and its documentation to reflect the correct usage. It also removes
moveSelectionStart/moveSelectionEnd/moveCaret (which aren't being used
yet), and updates WebFrameTest to show how these can be implemented via
selectRange.
