#20 grabber does not deal with nbsp

[John Blance]

The xtramsn html currently uses a non-breaking space to
placehold when the previous program continues into this
timeslot [blank table cell in viewed html]

The non-breaking space is not recognised by
htmlentities, and generates errors of the type:
WARNING:   is not mapped! Please check the code!
ERROR: You have encountered a bug!
list index out of range

a hacked fix could be something like:
