CharacterMap: Limit the number of results from the GUI character search

Browse source 
Past a few hundred matches, the search is no longer useful, and takes an
excessive amount of time to recalculate the column widths by measuring
thousands of pieces of text. 250 seems like a reasonable arbitrary
limit, and keeps things nice and snappy. :^)
