* Cleaner Rakefile

* Instead of "file" task for the _sinatra and _contrib directories,
* this now uses "directory" task which removes the needless checking if
* there is a directory named _sinatra/_contrib

* The default rake task also depends on "_contrib" task or else latest
* changes in contrib directories are not updated in the website

* Cleaned up CLEAN and CLOBBER directives by moving all individual
* calls into single calls
Regen prebuilt files
Markdown parsing is done by Kramdown now instead of Redcarpet.
Redcarpet does not parse inline HTML tags properly. Syntax
highlighting comes free with Kramdown in the form of Coderay gem.

The previous commit's generated html files were error prone. These are
due to improper parsing of Redcarpet gem and because of errors in
Readmes which have been corrected now.
deleted book.html and changes.txt since they are now linked
