Fix install error and convert README to reStructuredText

Early this week, GitHub user xX-Yoshi-Xx informed me that there was an
issue installing using my last commit. This was due to the script trying
to import a module from `src/m64py` before it was added to the path. So
I fixed that just by moving the import down a few lines.

I also rewrote the README in reStructuredText, since this is the
default Python markup format. I added some new content on using the
`requirements.txt`` file to install the Python dependencies as well as a
few other notes. I also did a few smaller things like making the
Changelog file in all caps like the other files.

+To install just the Python dependencies:
+
+``pip install -r requirements.txt --user``
+
+.. note::
+
+  This will not install the other system dependencies which are listed above.
+
+  You can also drop the ``--user`` flag and run as root user if you want to
+  install system-wide, but this is not recommended, as this will likely
+  screw up your distro's package management.
+
+Install
+=======
+
+First, run ``python setup.py build`` followed by  ``python setup.py install``
+to install
+
+.. code::
+
+  python setup.py build
+  python setup.py install --user
+
+.. note::
+
+  If you use the ``--user`` flag, make sure ``~/.local/bin`` is in your
+  user's path environment variable.
