ASH 2 - Another Sophisticated HUD

Colors have been greatly reworked in this update.

Change log:

• Fixed order of drawing text and background (HUD text is drawn after background which improves visibility)
• Color settings for HUD text color and HUD background color are split into actual color and alpha value
• Colors are handled as colors in ModMenu (see ColorPicker)
• Alpha values for text and background can be set by command or ModMenu

So new commands are:

/ash2backgroundalpha

/ash2textalpha
