This patch was created using

  find -name *.v | xargs -L 1 awk -i inplace '{from = 0} /^From/{ from = 1; ever_from = 1} { if (from == 0 && seen == 0 && ever_from == 1) { print "Set Default Proof Using \"Type*\"."; seen = 1 } }1 '

and some minor manual editing

Thanks to Amin Timany for the suggestion.

turns out we can import with shorter names (and we actually already do that frequently in "From Coq Import")

Also, make our redefinition of done more robust under different
orders of Importing modules.
