Update lg-remote-control.js

[vandalon]

Hi,

I've replaced some icons and changed some source icons so that they work better on a mobile phone (iPhone at least).

• Changed the menu arrows with chevrons, they are a big bigger.
• Replaced the SOUND button with an icon
• Replaced the INPUT button with an icon
• Replaced Back with an icon on several places
• Replaced INFO button with an icon
• Replaced the P with an P-icon, so it looks a bit bigger.
• Replaced the word "SOUND" with "sound" so it fits when using it on a mobile device (ha IOS app and mobile website).

Hope you like what I did :)
