app: implement tool undo for gradient editing in the blend tool
Move the tool undo functionality of the blend tool to the editor,
and add support for undoing gradient edit operations. Each undo
step that affects the gradient holds, in addition to the line
endpoint poisitions, a copy of the gradient at the beginning of the
operation, as well as necessary information to allow the selection
to "follow" undo. When undoing the operation, the saved gradient
is copied back to the active gradient.
To avoid all kinds of complex scenarios, when the active gradient
changes, or when the gradient is modified externally (e.g., by the
(old) gradient editor), all undo steps that affect the gradient are
deleted from the history, while those that affect only the endpoint
positions are kept.
