I believe nearly any time a token > 100 characters in length is
produced, it's a bug in the analysis that the user is not aware of.

These long tokens cause all sorts of problems, downstream, so it's
best to catch them early at the source.

We can accomplish this by tacking on a LengthFilter onto the chains
for StandardAnalyzer, SimpleAnalyzer, WhitespaceAnalyzer, etc.

Should we do this in 2.3? I realize this is technically a break in
backwards compatibility, however, I think it must be incredibly rare
that this break would in fact break something real in the application?
