Title: Improved project API

#### 1.) bugfix if `default-directory` is "~/"

This resulted in an endless loop. We now expand the path to git rid of this edge-case.

#### 2.) `(cabbage-project-p)` checks if a project is found

This is a simple function to check if cabbage can detect a project or not. It must be used as a guard to prevent calls into the project API when no root can be found.

#### 3.) `(cabbage-project-expand-path)` builds relative project paths.

This function is similar to Emacs `expand-path` with the difference that it builds relative paths to the current `(cabbage-project-root)`. Note that this function throws an error when no `(cabbage-project-root)` can be found.
