SheetViewOptionPtr: document that it is a superset of SheetViewOption

Add {G,S}etSheetPrOptions() to allow to set FitToPage for printing

Document in type system (not just in text for humans) that
all SheetViewOptionPtr are also SheetViewOption (well, if not nil).
This improves documentation visible with godoc but this simple change
also allows more flexibility to manipulate SheetViewOption programatically
such as saving and restoring values:

	var opt excelize.ShowFormulas
	opt = new(excelize.ShowFormulas)
	_ = xl.GetSheetViewOptions(sheet, -1, opt)
	_ = xl.SetSheetViewOptions(sheet, -1, opt)

Add SetSheetPrOptions and GetSheetPrOptions to allow to set options on
<sheetPr> and <pageSetUpPr>.

The following options are implemented:
- CodeName (string)
- EnableFormatConditionsCalculation (bool)
- Published (bool)
- FitToPage (bool)
- AutoPageBreaks (bool)

Add SetSheetViewOptions()

Two new methods:
- SetSheetViewOptions(sheetName string, viewIndex int, opts ...SheetViewOption) error
- GetSheetViewOptions(sheetName string, viewIndex int, opts ...SheetViewOptionPtr) error

The option values are given by the user through types that have privates methods
that implement the private SheetViewOption and SheetViewOptionPtr interfaces:
- DefaultGridColor(bool)
- RightToLeft(bool)
- ShowFormulas(bool)
- ShowGridLines(bool)
- ShowRowColHeaders(bool)

Examples:
    err := xl.SetSheetViewOptions("Sheet1", -1, excelize.ShowGridLines(true))

    var showGridLines excelize.ShowGridLines
    err := xl.GetSheetViewOptions("Sheet1", -1, &showGridLines)

Fixes #145.

Add missing XML attributes `customWorkbookViews` and `customWorkbookView` in the workbook, relate issue #152.
