Put the title into the .Doc variables as well.
Changed the test template file to use new names.

Changed the tests accordingly.

Created a struct containing middleware.Context, Title, Markdown and the
variables from the user to use to render the template.
The title now can be accessed via {{.Title}}.
The variables can now be accessed via {{.Var.myVariableName}}.

Created sample files for the test

Moved the Context type to middleware and exported it.
Users can use .Include and others in browse directive templating
Created test for the templates directive.

redir: Preserve query string on catch-all redirect (fixes #180)

Use path.Join and then check if the request had a slash at the end to
place it again.

Used http status code instead of a hardcoded value.
Used url.Parse instead of url.ParseRequestURI, so that you can parse
both absolute and relative URL.

The get parameters are now forwarded when redirected.
Added some tests to validate this behavior.
