Allow mpv-1.dll to be placed in python script directory (#96)

Windows: Look for DLL in script directory

Loading DLLs through ctypes on Windows is a mess. ctypes looks in PATH, which is different from the Windows built-in DLL loading system. By default ctypes looks next to python.exe, but you might not want to install python script dependencies next to the system-wide python interpreter.

This commit adds a fallback looking for mpv-1.dll in the same directory the mpv.py script is placed in to allow people to use python-mpv with a minimum in configuration. You can still control loading behavior through PATH. For details on this, consult the following stackoverflow answer: https://stackoverflow.com/a/23805306
