Fix name highlighting breaking emotes

Fix name highlighting when emotes are involved.  When the emotes were
moved to subfolders the channel name was put into the URL of the emote
image.  If a user with that name joined the chat, all of the emotes in
that folder highlighted the name in the URL, breaking the <img> tag.

This change removes the regex used to identify and replace the user's
name and instead works on whole words delimited by spaces.
