Add Virtual Joysticks for the Mobile App

[awilwayco]

• Note: Need to add multi-touch functionality to the mobile app for this to work! (To use two virtual joysticks at once)
• On a mobile device, when a user has selected a blimp AND then clicks on the Controller Input Display button, a new UI appears (A new Page not accessible through the sidebar menu!)
• The new UI includes:
• Name Button for the selected blimp
• Catching Button for the selected blimp (new button)
• Shooting Button for the selected blimp (new button)
• State Button for the selected blimp
• Auto Button for the selected blimp
• Calibrate Button for the selected blimp
• Vision Button for the selected blimp
• Virtual Joysticks that control the selected blimp (new component; not a button)
• Exit Button (X) that deselects the blimp and goes back to the main page
• Try to include the following if space on the app allows:
• Barometer Button
• All Blimp Buttons (Goal, Enemy, All Auto, All Manual)
• Logo
• Sidebar Menu
• Test performance and functionality when multiple blimps are being controlled using htop
