Remove wrong paren-close from example project file
Fix (defjekel) macro

It returned nil before. Obviously I was missing the `(progn) to return an
expression that actually changes the org-publish-project-path.
Implement (jekel/publish)
Remove less publishing in favor of sass
Fix documentation text
Renamed package function prefix to "jekel--"
Simplify newly created projects
Remove obsolte commented code
Set layouts-directory when publishing markup/org
Remove duplication in jekel--render-layout
Remove helper function stubs

Those are defined as locally bound functions
in (jekel--define-markup-helpers).
Add (jekel--define-markup-helpers) macro

This macro binds some functions locally via FLET to be used in markup.el
markup generation.
Add (jekel--define-markup-helpers)

Generates the markup inside the (jekel--define-markup-helpers) macro so
I can use the markup helpers inside my templates/layouts.
Remove obsolete variables for format
Remove whitespaces and line breaks
Use (render-layout) helper in example project
