Removed type casting

If these values (i meant BroadcastRGB and SuperAdminChatRGB) uses only like a 'byte', why they are storing like a 'float'

On my linux machine (ARMv7, ubuntu server 13.04) it causing errors. Of course, those errors is in mono library. And it's in reading 'double/float' from strings. But storing 'byte' like a 'byte' is a right decision, isn't it?)))
