fix(AnalyticalTable): Show selection column with select all in header

[MarcusNotheis]

For compliance with fiori specs, show an additional selection column as first column to show CheckBoxes and a CheckBox in the Header for selecting/deselecting all rows

You can hide this column by setting the noSelectionColumn prop on the table.

Closes #302

two things.

1. Is that empty column on the left for SINGLE_SELECT there on purpose? Is that part of the specs?
2. The additional column doesn´t seem to play well together with the new scaleWidthMode feature. The table should be stretching for the whole available width, but it doesn´t.

Yes, that is by design (also compare the sap.ui.table.Table)

2. The additional column doesn´t seem to play well together with the new scaleWidthMode feature. The table should be stretching for the whole available width, but it doesn´t.

I'll have look at that one
