Recent newpot rethink and redo

Recent newpot rethink and redo

The newpot build command has a tendancy to cause more harm than good in
certain cases.  Basically, if run with a translation-toolkit of 2.0+
after originally using 1.x, you end up with different POT formatting
which in turn breaks existing translations for those strings.

I talked this over with Ben Shum, and he advised we simply stop doing
POT updates in point releases for now.  I agree, and this reversal is
my attempt to stop the bleeding.  It tries to remove any unneeded POT
changes from recent history, while also keeping completely new strings
that have already snuck in.

This reverts commit a37154508d8fc078b5d9bae5ada105a534c13ecd.
This re-does commit 4e0b9d31cdbda3c356b22778b361ae4e60375255.
