UI elements off screen

[medphysJH]

If the application isn't in full screen or is being displayed on a different sized screen not all the UI elements are visible.
Add scroll bars to the display if any elements are not displayed.

Added UI resizing. Controls such as buttons and graphs will automatically resize itself according to window size. Currently works fine if Scaling in windows display settings is set to 100% and works for any resolution (e.g. 2560x1440 or 1920x1080 etc.)

Window Minimised:

Window Full Screen:

Also added scroll bars to settings menu:

Still need to fix issues with scaling if the PC's scaling is not set to 100% (sometimes people will be using 125% scaling which causes the graphs to not resize properly however all buttons should be accessible).
