template: added css file for markdown files

Very preliminary. I want to make the text bigger, and use a better font
like verdana
added a new root-level folder "micro"

For micro-sized projects that are too small to be considered a project
but too big to be considered a single one-off script
micro/: better wording in the README
added a new micro project "wmirror"

for fully locally mirroring web pages
Added `misc` directory
