Integrate `go-git` into the application, and use it to `git clone`
cheatsheets when the installer runs.
Previously, the installer required that `git` be installed on the system
`PATH`, so this change has to big advantages:
1. It removes that system dependency on `git`
2. It paves the way for implementing the `--update` command
Additionally, `cheat` now performs a `--depth=1` clone when installing
cheatsheets, which should at least somewhat improve installation times
(especially on slow network connections).
Fix an issue whereby colorization would output ANSI codes if a pager was
not configured.
The solution here is to stop guessing about the state of the user's
system at runtime, as well as the user's intention. The installer now
chooses an appropriate installer when generating configs, and no longer
bothers searching for pagers at runtime.
Fix an issue whereby the installer installed cheatsheets into the wrong
directory on Windows. This occurred because previously `path.Join` was
used where `path/filepath.Join` should have been used.
This matters, because the former always uses `/` as the path separator,
whereas the latter will use `/` or `\` as is appropriate for the
runtime environment.
This should resolve bullet point 4 in #665.

feat(config-init): platform-specific pathing
Update `--init` subcommand to rely upon the same platform-detection
intelligence that was previously implemented by the "installer".
The installer and `--init` should now produce identical config files.

fix(tests): fix `config.Paths` tests
Refactor `config.Paths` (by externalizing a call to `homedir.Dir`) to
decouple it from filesystem paths, thus facilitating cleaner unit-tests.

feat(config): refactor config path detection
Previously, failing other checks, on Unix and BSD systems,
`config.Paths` would attempt to compute the user's home directory by
reading the `HOME` environment variable.
This change deprecates that approach with a call to `homedir.Dir`, which
is used elsewhere throughout the application.
