[portfolio] named variables cause errors in "+="

Doing the block=equivalent of

foo = foo + 100

fails with the error below:

TypeError: 'str' object is not callable
space, 32<flags 0 of type GdkModifierType>
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)

/home/olpc/Activities/TurtleArtPortfolio.activity/tawindow.py in keypress_cb(area=<gtk.EventBox object at 0x9f86cd4 (GtkEventBox at 0xa3e4340)>, event=<GdkEvent at 0xa3e4390>, tw=<tawindow.taWindow instance at 0x9f76bcc>)
    442     if tw.firstkey: newnum = selblock.check(keyname,tw.defdict[selblock.name])
    443     else: newnum = oldnum+keyname
--> 444     setlabel(tw.selected_block, selblock.check(newnum,oldnum))
        global setlabel = <function setlabel at 0xb609317c>
        tw.selected_block = <tasprites.taSprite instance at 0xa16cfcc>
        selblock.check = ''
        newnum = 'None '
        oldnum = 'None'
    445     tw.firstkey = False
    446     return True

the equivalent 'code' works with box1 and box2

This is fixed as of Version 7 (with the new arithmetic operators). I haven't propagated the changes back into Turtle Art yet--awaiting feedback from the field as to whether the new approach is OK with the teachers.

Moving to 0.86.

fixed since new arithmetic operators in place
