Added sound settings page

+ added sound setting page
+ added sound setting icon
+ moved sound settings from interface settings

Added master volume

+ added master volume slider.
+ volume can be changed by sliding bar or by using the spin box
+ Preview of  volume will be played when dragging and releasing bar.

Added checks for qt4

Qt4 does not have support for setting the volume without some lengthy
work around, I have disabled volume control for qt4 users and have
mentioned that "Master volume requires qt5".

Updated sfx

+ removed all old sfx
+ added new end step and tap sound
+ tap/endstep sound has a timer on it to prevent spamming
+ test sound engine will now use endstep sound

Made end step sfx softer

end step felt too harsh

Added player joined sound

+ added a sound for when a new player joins a room

Updated

Was missing a sound when a player joins

Made end step softer

Made end step even softer

updated sound again
