Title: Added a default encoding for RDoc parsing in gemspec file

This essentially will run the `rdoc` command with the `--encoding=UTF-8` parameter
during the installation of the gem which will force utf-8 encoding irrespective of the
locale settings of the user.

This will solve [issue#504](https://github.com/sinatra/sinatra/issues/504)
