Luc Vanlerberghe updated LUCENENET-493:
---------------------------------------

    Attachment: Lucenenet-493.patch

Makes lucene.net locale/culture independent (like the java version).
Solves a few testcases that fail when run on a machine with a non-US culture.

> In Java, conversion of the basic types to and from strings is locale (culture) independent.
For localized input/output one needs to use the classes in the java.text package.
> In .Net, conversion of the basic types to and from strings depends on the default Culture.
 Otherwise you have to specify CultureInfo.InvariantCulture explicitly.
> Some of the testcases in lucene.net fail if they are not run on a machine with culture
set to US.
> In the current version of lucene.net there are patches here and there that try to correct
for some specific cases by using string replacement (like  System.Double.Parse(s.Replace(".",
CultureInfo.CurrentCulture.NumberFormat.NumberDecimalSeparator)), but that seems really ugly.
> I submit a patch here that removes the old workarounds and replaces them by calls to
classes in the Lucene.Net.Support namespace that try to handle the conversions in a compatible
way.
