Missing vertical_alignment

[Coyote-31]

• Add vertical_alignment in instantTextBoxType
• Test in other scope

Exemple in macrobuildinterface_override.gui :

instantTextBoxType = {
			name = "company_leader"
			position = { x = 15 y = 46 }
			textureFile = ""
			font = "vic_18"
			text = ""
			maxWidth = 170
			#c maxHeight = 18
			maxHeight = 40
			format = left
			#c vertical_alignment = bottom
                        vertical_alignment = center
			vertical_alignment = top
			fixedsize = yes
			allwaystransparent = yes
		}
