fix in SpaceParser when parsing json format: floating point values such as 1.123e+01 where not correctly parsed ('+' character was not correctly parsed)

added to Space: some methods for searching a field with ignoring case:
Space * get_object_field_nc(const wchar_t * field)
Space * get_object_field_nc(const std::wstring & field);
const Space * get_object_field_nc(const wchar_t * field) const;
const Space * get_object_field_nc(const std::wstring & field) const;
