MantidPlot: Allow objects to connect to PeakPickerTool range changes

[Mathieu Doucet]

Letting an object connect to a PeakPickerTool signal giving selected range updates will be necessary for reflectometry. At the moment, PeakPickerTool only talks to the fit browser.

Design note: it would be very nice to separate the PeakPickerTool from the fit browser so that it can be re-used independently.

Expose selectMultiPeak to python. Re #3425

[Mathieu Doucet]

To test, run the following script in ManditPlot. The updated range should be printed in the Scripting Console as you drag the vertical delimiters.

from PyQt4 import QtGui, QtCore
import time

def print_range(xmin, xmax):
	print xmin, xmax

CreateWorkspace(DataX=[1,2,3,4],DataY=[1,1,1],DataE=[1,1,1],NSpec=1,OutputWorkspace="ws")
qti.app.connect(qti.app.mantidUI, QtCore.SIGNAL("x_range_update(double,double)"), print_range)
g = qti.app.mantidUI.pyPlotSpectraList(["ws"],[0],True)
qti.app.selectMultiPeak()

This doesn't seem to update the scripting console but updates the values in the fit browser. Is this what's supposed to happen?
