Update card_draw.lua (#1236)

Bug fix: canvas text was drawn even when card was undiscovered.

New functionality: easy text alignment: rather then creating a new table for text_transform whenever the text changes, this way you can simply set text_h_align and text_v_align once.

text_h_align can be 'left', 'center' (default behaviour) or 'right'
text_v_align can be 'top', 'middle' (default behaviour) or 'bottom'
