Re-organise "Coding Style" section

This doesn't add or remove any rules, it just groups them together under: Layout - Indentation - Inline - Newlines Maximum Line Length Inspired by the RuboCop [1] and AirBnb [2] styleguides.

+## Layout

+### Indentation
 
 * Use soft-tabs with a two space indent.
 
-* Keep each line of code to a readable length. Unless you have a reason to, keep lines to a maximum of 118 characters. Why 118? That's the width at which the pull request diff UI needs horizontal scrolling (making pull requests harder to review).
-
-* Never leave trailing whitespace.
-
-* End each file with a [newline](https://github.com/bbatsov/ruby-style-guide#newline-eof).
-
-* Use spaces around operators, after commas, colons and semicolons, around `{`
-  and before `}`.
-
-``` ruby
-sum = 1 + 2
-a, b = 1, 2
-1 > 2 ? true : false; puts "Hi"
-[1, 2, 3].each { |e| puts e }
-```
-
-* No spaces after `(`, `[` or before `]`, `)`.
-
-``` ruby
-some(arg).other
-[1, 2, 3].length
-```
-
-* No spaces after `!`.
-
-``` ruby
-!array.include?(element)
-```
-
 * Indent `when` with the start of the `case` expression.

 * Use empty lines between `def`s and to break up a method into logical
   paragraphs.

 ## Classes
