* support `-html` flag to render output as HTML
This addresses issue #69 to support HTML output.

* improve tests to exercise outputs
Previously, the tf-summarize tests did not exercise the tool's ability
to summarize plan outputs. This fixes that!
* ensure 'make help' outputs details on all targets
By adding a code comment in association with all Make targets, `make
help` now documents all targets:
```
$ make help
build                          build the binary
example                        generate example Terraform plan
help                           prints help (only for tasks with comment)
i                              build and install to /usr/local/bin/
install                        build and install to /usr/local/bin/
lint                           lint source code
test                           go test
```
* put HTML resources in <code> within summary
This makes the HTML output a bit more consistent with output elsewhere.
* protecting against stale tests runs
This protects against false positives running the tests.

ensure multiple markdown tables are rendered (#62)
This seeks to fix issue #61 by printing all output to the `io.Writer` passed to
`writer.TableWriter#Write`. This ensures multiple, distinct markdown tables are
printed, even when `tf-summarize` is invoked with both `-md` and `-out` flags.
Previously, `fmt.Println()` was used to separate the markdown tables,
but this is insufficient when `-out` is used with a non-STDOUT writer, as is the
case when writing output to a `-out`-specified file.
