SANS support slicing event mode data

[Gesner Passos]

(In #8505) There was a considerable work in this ticket. So, I decided to split it, in order to help the tester to follow what was done and test this ticket.

[Gesner Passos]

The following script slices the input workspace before applying the reduction.

import ISISCommandInterface as i    
reload(i)
MASKFILE = FileFinder.getFullPath('MaskSANS2DReductionGUI.txt')

i.SANS2D()
i.MaskFile(MASKFILE)
i.AssignSample('22048')
i.AssignCan('22023')
i.SetEventSlices("0:300:450")
red = i.WavRangeReduction()

[Gesner Passos]

The user defined that we must not slice the can, only the sample.

Refs #8528. Avoid slicing the sample

By making the can workspaces histograms, in loading time, we ensure that they will not be sliced in any time during reduction.

Refs #8528. Correct error related to reduction in batch

Because assignSample cleaned the slices definition, it lacked support for slices. Now, it is cleaned on loading mask.

There is a systemtest as well.

Running the following in the console:

from mantid.simpleapi import *

import ISISCommandInterface as i    
import SANSBatchMode as batch

BATCHFILE = FileFinder.getFullPath('sans2d_reduction_gui_batch.csv')

i.SANS2D()
i.MaskFile(MASKFILE)
i.SetEventSlices("<451")
fit_settings = batch.BatchReduce(BATCHFILE, '.nxs',saveAlgs={}, combineDet='rear')

gives the following error:

ValueError: When converting parameter "StartTime": Selected value -1 is < the lower bound (0)
  at line 11 in 'New script'

[Gesner Passos]

It seems to have lost one commit:

Refs #8528: Parse correctly -1 option SANSUtility

It translate the -1 option. Put some words to explain the code as well.
