(No actual changes.)

o comment blocks filled arrays disappear
o empty array tags disappear
o empty value tags collapse

This only leaves comment blocks in empty tags, which create
whitespace noise, which fucks up the config.xml real bad,
rippling through to the code that deal with is_array, isset
and actual = array() assignments to fix the faulty config.
Will clean this up one by one later.

Leave the rest of the changes from master out for the sake
of further testing...

Our new config system writes two spaces, so this makes it easier to
diff against the factory reset config.

Also enables French for 15.7.14.  :)

Yay, thanks, Wallace!

This is pretty good to have, for now don't merge the top half,
since it is intermingled with submenu redesign.

128M has some crash reports attached, but "modern" i386 systems
have more RAM to spare, too.  Also remove two old expansions to
64M, which are now restrictions, because when they were introduced
the memory limit was 32M.  ;)
