Templating

[peppidesu]

As much as i like the macro idea, it isn't nearly as versatile as proper templating.

Instead of reinventing the wheel here, we should instead use something like Tera / Handlebars to do this for us.

I agree that webby needs templating, but I don't want to just take existing systems at face value. I'd rather design something more carefully.

Couple of things:

• I don't want to use tera, it pulls in a ridiculous amount of dependencies and part of the design of webby is that it's fast to compile (see list a the bottom of this comment).
• Templates should integrate with webby.toml. Something like template = "path/to/my/template.html".
• I'd like the syntax to feel more HTML-native. I actually don't like flask-style {% variable %}, it's annoying to type and I've had it break some formatters. I'm wondering if we could use something like <!TEMPLATE.variable>.

And while we're at it, I feel like macros could use a bit of a redesign. Since one of my goals is to allow custom macros in Lua, I'd like Lua to be able to integrate easier into webby.
