Allows emotes to be uppercase by changing early lowertext() (#63909)

Makes the message of emotes not lowercase by moving the lowertext(act) in emote.dm lower.

And yes, it still recognizes emotes. *coUGH will still happen.

For the guys up here, mainly code cleanup. This PR was originally made for skyrat, because there you can press T and then type "*me blah blah blah". Due to the way this works, before this PR, you couldn't put any capitalization after *me because it'd lowercase it.
