Resolves #160

The `setup.py` script no longer attempts to install files to privileged
system directories. (Previously, it attempted to do this in order to
enable command-line autocompletion.) In lieu of doing this within the
installer directly, I have simply included brief instructions explaining
how to configure this manually.

Version bumped accordingly.

+### Enabling Command-line Autocompletion ###
+The `cheat/autocompletion` directory contains scripts to enable command-line
+autocompletion for various shells. To activate autocompletion, simply copy the
+appropriate script to the appropriate path on your system. (The "appropriate
+path" will vary on a per-platform basis, so this documentation shall not
+speculate as to where that may be.)
