mkdocs-ezlinks-plugin-0.1.12

This is a bugfix release.

Issues addressed:

• GH issue #25, Absolute links not using http:// or https:// are treated as relative.
  Dev @robbcrg (thanks!) reported that links with protocol schemes other than those two should also be treated as
  absolute links. The regex will exclude any link from a conformant protocol scheme from being converted using EzLinks.

• GH Issue #27, Dictionary file cache is not being leveraged.
  An inverted comparison led to the fast file cache lookup never really being exercised. Now, if a filename is unique, it will find it in the fast file cache first, saving a more expensive full trie lookup.
