using pandoc markdown with bashblog

When I first ran bashblog, it didn't seem to know how to 
find the markdown parser on this system, but `pandoc` is 
installed.

To solve this, I wrote a simple wrapper script to accept 
the calling convention that bashblog accepts and then to 
call pandoc: 

```sh
#!/usr/bin/env sh

# Adapter so that bashblog can use pandoc markdown.

/usr/bin/pandoc \
	-o - \
	--from=markdown \
	--to=html \
	"$@"
```

I stored that path in the `markdown_bin` variable
in my blog `.config` file, and set file
permissions:

```bash
chmod u=rwx,go=r "$markdown_bin"
```

Now I can write posts with Markdown!
