Finish dashboard page

[tommyah]

This issue is in reference to the following tasks:

Technical wiring:

• Make the sidebar list of the stats page properly reflect the stocks owned by the player
• Making each stock clickable and update the overview, including the graph.
• Add search bar to the sidebar, for quick searching
• Add a button to change type of graph display (since purchase, 1 week, 1 month, 1 year).
• Add functionality for selling shares (portfolio?)
• Add a text field above buy/sell to make it possible to select quantity to buy/sell

UI:

• Make sure the layout is responsive.
• Make sure the page is intutive and includes all the information a player needs
• Make sure the text is not too small
• Color profile should be in line with the principles of universal design
• Overall layout should be easy to understand

Extra:

• Feedback system for immediate button response (optional)
