[Tilesathome] Inkscape locale issues. what were they?

[spaetz]

Inkscape

1) we set setlocale(LC_ALL to  $Config->get("InkscapeLocale"); before each call
2) in the commando line we use $Config->get("i18n") ? "LC_ALL=C " : ""

This gets the redundant redundancy award with a bonus for obfuscation. :-)
Why 2 settings for 1 thing? 

This is not just ugly, but as we reset the locale to the old locale (which seems to return German on German computers) after each inkscape call with:
  setlocale(LC_ALL, $oldLocale);

This leads us to insert the dreaded comma numbers as boundary coordinates in the .osm file which or/p complains about.

Why did we need to set the locale for inkscape again? I recall some bugs but nothing specifically, and it's not documented in the code (tss, tss, tss).

Do we really need LC_ALL or would some LC_NUMERIC suffice? What works on German boxes, German locales or 'C'?

Let's fix this the right way.
