Update URL parsing

[blmayer]

My shot at fixing the URL parsing, and relative URL handling.

8a3f9bc seems to be an improvement, but not yet perfect.

URL from command line

✅ ./astro derelict.garden
✅ ./astro gemini://derelict.garden
✅ ./astro derelict.garden/astro.gmi
✅ ./astro gemini://derelict.garden/astro.gmi

URL followed by navigation

✅ ./astro derelict.garden + g + 1
✅ ./astro gemini://derelict.garden + g + 1
❌ ./astro derelict.garden/astro.gmi + g + 2 (page does not render)
❌ ./astro gemini://derelict.garden/astro.gmi + g + 2 (page does not render)

URL + navigation + back button

❌ ./astro derelict.garden + g + 1 + b (blank page, q does not work)
❌ ./astro gemini://derelict.garden + g + 1 + b (blank page, q does not work)

In this case with the back button, it seems that path is getting populated incorrectly which leads to Page not found! and then astro tries to go back again which puts it in a very weird state.

Nice tests, I'll use them to check my progress. I think, if I'm not mistaken, that this

./astro derelict.garden/astro.gmi + g + 2 (page does not render)

Selects a HTTP link, which is not supported by astro. I'll put a check for other protocols.

It passed your tests. Thanks!
