added to Space: long double to Space::Value and methods for converting from/to long double
added global methods for converting float/string double/string and long double/string (convert/double.h|cpp):
float to_float(const char * str, const char ** after = nullptr);
float to_float(const wchar_t * str, const wchar_t ** after = nullptr);
double to_double(const char * str, const char ** after = nullptr);
double to_double(const wchar_t * str, const wchar_t ** after = nullptr);
long double to_long_double(const char * str, const char ** after = nullptr);
long double to_long_double(const wchar_t * str, const wchar_t ** after = nullptr);
float to_float(const std::string & str, const char ** after = nullptr);
float to_float(const std::wstring & str, const wchar_t ** after = nullptr);
double to_double(const std::string & str, const char ** after = nullptr);
double to_double(const std::wstring & str, const wchar_t ** after = nullptr);
long double to_long_double(const std::string & str, const char ** after = nullptr);
long double to_long_double(const std::wstring & str, const wchar_t ** after = nullptr);
std::string to_str(float val);
std::wstring to_wstr(float val);
std::string to_str(double val);
std::wstring to_wstr(double val);
std::string to_str(long double val);
std::wstring to_wstr(long double val);
