v0.0.3

URL decode and strip URL query parameters when doing markdown file-exists check.
Basically, you can have weird non-illegal OS URL-encoded file-name characters in your markdown file-name, and script should now handle it.
You could name your markdown file Stuff&Things.md, and httpmdhtml.server should still work as expected.
You could GET request Stuff&Things.md?query=cool and httpmdhtml.server should strip query parameters from request as http.server does.
