Added a static assets handler for css/js.
Added a web struct.

Right now the web struct only contains one variable, seeing if you
want to see a front end besides the API. It is set to true as default
in the example config, but it can be set to false if one wishes.
Only server / and /static if the config says it's okay.
Added basic style and index file
Front-end design
Refresh angel/core also on the / page
Add config option when making a config file in the func.
Only parse html templates
