Use DLL's folder to look for ini file

[sytelus]

The xinput DLL's folder should be included for ini search. This is very important for plugins (for example, Unreal plugins) where DLL path is not same as exe path and DLL is loaded dynamically. In these cases, plugins have no knowledge or control over exe path and its not desirable to modify its folder anyway.

I've this change done but looks like instructions to build and test are outdated or non-existent so I'm unable to test below change. Hopefully, the change is trivial to add, however.

Proposed change in x360ce\x360ce\dllmain.cpp

VOID InitInstance(HMODULE hModule)
{
	IniFile ini;
	std::string inipath("x360ce.ini");
    if (!ini.Load(inipath)) //<--------- look for ini module's directory
        ModuleDirectory(&inipath, hModule);
    if (!ini.Load(inipath))
		CheckCommonDirectory(&inipath, "x360ce");
    if (!ini.Load(inipath)) return;
