Changes to Sorting Algorithm Dropdown Menu

[skbedi]

Changes:

• Sorting Algos are now sorted by complexity and then alphabetical order
• Grid is now a list of all the sorting algos in order

Why: (resolves #175)

• This issue asked for improvement in the selection dropdown so it is easier to find the algorithms and a design change "to fit all algorithms and their names"
• This new design resolves both of these issues

How:

• after creating new branch called dropdown, first sorted the algorithms in algs.py (comments in the doc show how)
• in display.py altered class DropdownBox(InputBox): to fit new requirements.

**Testing: **

• visually tested list to make sure all options were available and clickable
• clicking on each option chose the right sorting algo.
