Adding one typeselect future and one test showing its pointless

twoTypeSelects.chpl shows that the current implementation of
type select does not support multiple type selects in a single
Chapel program.  D'oh!  It's probably a five-minute fix to get
this working if one cared to.  By the time I'd written up the
description in the .future, it seemed like I also had the
solution.  But...

deprecateTypeSlect.chpl shows the syntax I'd prefer to use for
"type select" statements and was intended as a feature request
future; but it turns out to work.  So it raises the question
"Do we even need a type select anymore?"  Until someone argues
convincingly otherwise, my answer is "no, it seems like we
don't."
