MsgBox needs to support the Size property

[mkromberg]

{"WC":{"ID":"MB","Properties":{"Btns":"OK","Caption":"Ribbon images not found","Default":["Size",[100,500]],"Event":[["MsgBtn1",""]],"Posn":[0,0],"Style":"Error","Text":"C:/devt/ewc/demo/images/ribbonimagez/16x16/*.png","Type":"MsgBox"}}}

Gives an MsgBox which is too small to display the text.
