Make xml (and CSV) parsing use 'g_ascii_strtod()' rather than 'strtod()'

GTK messes up the standard C library locales by default (instead of just
taking locale information into account internally).  Which breaks
'strtod()' and 'printf()' etc.  Since they screwed that up, they then
added helper functions for undoing that braindamage.  Use it.

I'd like to blame the GTK people, but the standard C libary people bear
*some* responsibility for this.  One of the reasons why people do not
use "setlocale()" in many normal programs is exactly because it messes
up core libc functionality - with number conversion being the main
thing.

Doing things like converting numbers in a locale-specific manner is
something people do want to do, but not *always*.  So the C library
locale code should always had defaulted to C locale, with some *extra*
marker (like a printf/scanf modifier) to say "print/scan in the current
locale".

Because many things absoilutely need to be non-localized.  You don't
want your internal file format to magically change just because you want
to show things to the user in France, for example.
