GetClientRect

GetClientRect returns the co-ordinates of a window's client area - ie. the area of a window minus the title bar and the window's borders.

GetWindowRect returns co-ordinates indicating the area of the whole window, title bar and border included/

This will provide for:-
a more accurate/simpler auto-clicker in DeckExporter
accurate positioning of overlays

This also eliminates the need for both fullscreen and windowed variables in config.xml for the co-ordinates of controls in Hearthstone.
GetClientRect fix

A more accurate way of obtaining the screen area the Hearthstone game is
using.

Overlay positions are now better confined to game window (all
resolutions, dpi settings)
Removes the need for fullscreen variables of positions of controls in
config
