prettify login shell selector

[simonLeary42]

• added a .code CSS class so that any element can be code
• removed width: 100% from <select> and <input type=select>
• added extra padding (more left than right) to <select> and <input type=select>
  • more left than right because the right has the downward arrow symbol
• modified the account settings login shell select to have the code class
