SDL_GetPrefPath should return a c_char_p

[benob]

It currently returns a LP_c_char but it should really return a c_char_p.
Then, the user then has to free it as per the documentation.

[a-hurst]

Hopefully fixed in the latest commit, thanks for the report! Also, since ctypes is just returning a byte string it's no longer possible to call SDL_free on it (since SDL_free expects a pointer to the character array), but I'd imagine ctypes handles that for us anyway since it's converting the returned array to a string for us.
