Remove exclamation point at the end of !settitle in main.js lang file

It’s just a bit confusing, when one of my mods changes my title it makes me think they typed an exclamation point at the end.

If you use| !settitle Streaming Games
The bot replies| Changed the current title to: Streaming Games!

I know I can use a custom lang file and change this for my instance, but it would remove some ambiguity from the main release if the exclamation was removed from the release. It’s main.js line 263

It may be worth removing the exclamation from !setgame as well, (line 261) but that one isn’t as confusing.
