proposed change to filler

specify count (length) of string to be generated, since typical text blocks (layouts) use length limits (i.e. Headline 125 characters). Use of previous version specifying count of words too hard to determine how to fit within layout block (i.e. headline). This revision just generates filler up to max count, no cpu cycles wasted on exploding, randomizing and imploding commands, since filler is only temp for layout visualization & repeated passages shouldn't bother anyone ;)
