add recipies to install less & jekyll

Add a cookbook "apt" its from https://github.com/opscode-cookbooks/apt its just to prepare the system with some basics which make it easier to create the cookbooks for Jekyll & less.

Add a cookbook "phpughh" which installs all dependencies which are needed to be able to do change on phpughh.phpugh.com repository.

Software:
* less
* jekyll

The "phpughh" is separated into different recipes, separated by task. Also added a basic attribute so the ruby package version which will be install is configurable.

So far tested everything. Had only an issue with invalid encoding in talks.md's files.

Everything documented so far if something is missing let me know. Also wrote a installation guide would be fine if somebody who is more fluent in English would review it.
