Refactor Sword::Compiler and rename it to Compile
Sword::MIME -> MIME
Rename Sword::Server to Serve
Start writing specs
Drop Sword::Helpers#package

It should be a plug-in, not a built-in feature.
Drop patches

There will be a new behaviour considering MIME types: now it is
text/html by default, so we don’t need Tilt patches. Compass patch
should be a sword/compass plugin, others like Stylus or Slim should be
enabled through Gemfile.
Drop Sword::MIME and include its parts to Sword::Template module
error.erb: <title> is 404 by default
Use Sword::Helpers as an object where rendering takes place
template.rb: MIME -> TYPE
Rewrite Sword::Serve in more concise refactored way

Now there is only #call module, Rack::Response is not used anymore,
SLASH is not used since paths like path//to///directory paths are
absolutely valid in Unix. More smaller minor improvements.
