Remove unnecessary conditional in Clickable
Remove unnecessary conditional in Clickable

Clickable had a conditional to look up the DSL on an object passed to it
instead of applying the clicking to the object itself. This was only needed
for the Shoes::Link class, and now isn't necessary there anymore. Hurray!

Resolves #293.
