static site generator

All files get copied from the write dir to the site dir

Markdown files get converted to html in the process

HTML is generated from template.html, with{FILENAME}(optional) and {CONTENT} getting replaced.

This markdown is non compliant and I don't care. *Emphasis*, **bold** and _underlined_ are implemented, as well as code. Standard ## Headers up to 6 levels, and ``` at the start of a line for code block (html <pre>) toggling. Backslashes for escaping may be added later. There are no lists, but also automatic line breaks everywhere, so they look fine without needing html lists

ideas:

/blog/post_1.md -> /blog/post_1/index.html
/blog/ferret.mp4 -> /blog/post_1/ferret.mp4

/blog/post_2/post_2.md -> /blog/post_2/index.html
/blog/post_2/cat.png -> /blog/post_2/cat.png
