Subject: Use Error & ErrorKind pair instead of simple enums

Each plugin should define its own errors with a respective variant
in the main ErrorKind of frippy.
A new procedural macro was added to reduce the boilerplate required
for new error system.
It can be used by deriving "Error" and adding a name for the Error
via the "error" attribute.

So far non of the plugins except for Url and Factoids
use their own errors yet.
