Remove unused arguments from mve_Init()

Before this change, mve_Init() took two arguments. Neither of the
arguments were ever used. This commit simplifies some code by removing
those unused arguments.

The main motivation behind this commit is to make it easier to make a
future commit. One of the arguments that this commit removes was named
dir. dir was a path to the movies/ directory. The future commit will
make it so that there can be more than one movies/ directory. Removing
dir means that I won’t have to mess with dir when I create that future
commit.
