Describe the bug
Whispering someone with a Spaced Name, doesn't store their information.

To Reproduce
Whisper someone that creates a 'spaced name' in whisper window.

Expected behavior
When you establish a conversation with Player A, it should return a 'history widget' at the top of the screen. This doesn't appear at all.

Additional context
From my digging, I reckon it is because of the env.character tag in WIM.lua differs from the fix mentioned in WhisperEngine, where it is:
user = string.gsub(user," ","") -- Drii: WoW build15050 whisper bug for x-realm server with space

See if this is fixed in the next version. I made some changes to how names are handled.
