Subject: [PATCH 1/3] Add vertical align property

Add support vertical align property (vertAlign) with possible values are superscript and subscript.

Use:
for entire cell
firstRow.font = { name: 'Arial', family: 2, size: 20, vertAlign: 'superscript'}

rich text:
worksheet.getCell('A10').value = {
'richText': [
	{'font': {'size': 12,'color': {'theme': 1},'name': 'Calibri','family': 2,'scheme': 'minor'},'text': 'This is '},
	{'font': {'italic': true,'size': 12,'color': {'theme': 1},'name': 'Calibri','vertAlign': 'superscript'},'text': 'superscript'},
	{'font': {'size': 12,'color': {'theme': 1},'name': 'Calibri','family': 2,'scheme': 'minor'},'text': 'and '},
	{'font': {'italic': true,'size': 12,'color': {'theme': 1},'name': 'Calibri','vertAlign': 'subscript'},'text': 'subscript'},
]
};
