Allow non-GET requests to use r.redirect with no argument, redirecting to current path
Add r.multi_route method to multi_route plugin, for dispatching to named route based on first segment in path

This makes it easy to handle the case where the first segment in
path matches the named route.
Make multi_route plugin route("route_name") method a request method instead of an instance method

I think I made a mistake making this an instance method instead of
a request method originally.  Methods related to how requests are
routed should be request methods, not instance methods.

This breaks compatibility with 0.9, but it's better to make this
change pre-1.0.
Add :escape option to render plugin for using erb templates where <%= %> escapes and <%== %> does not

Erubis has native support for escaping by default, but unfortunately
it is broken if you use postfix conditions inside <%= %>.  Add our
own Erubis::EscapedEruby subclass working around that issue.  While
there, optimize the generated template by using a local variable
instead of a nested constant lookup for each escape.
Add :content option to view method in render plugin to use given content instead of rendering a template

When using :escape, you can't use an inline template with <%= content %>
to render arbitrary content inside the default layout.  This lets
you provide the content to use if doesn't require a template rendering.
Enhance security section in README
Use more descriptive title tag on website
Add CONTRIBUTING file
Fix multi_route example in README
Update composition section of README
Try to improve description of Roda in README

This also has minor tweaks to the website for similar reasons.
Don't have :extension hash matcher force a terminal match

I suppose this makes sense in Cuba, where terminal matchers are
not the default, but since Roda has easy support for terminal
matchers, there's no reason for :extension to be different
than other matchers.
