Update player's name on user components and lobby members panel

[braem]

Closes #1162

Unfortunately there's no steam callback for changing names (at least from what I read of the steamworks API), so I took the approach of just updating it more often.

• Main menu user component updates when drawer is closed. Not on open as you can't see it with the drawer open anyhow.
• Profile page's user component updates when the tab is clicked on. For some reason OnPageShow isn't being called when opening the drawer though. Intentional?
• Lobby name & avatar now update with any lobby change.
• Fixed steam name being always being overwritten by user data in user component (SetUser sets the steam name then calls FillControlsWithUserData that overwrites it with the one in user data). Result though is us not using the locally stored username.

Checklist

Doesn't PersonaStateChange_t callback get fired for local player?

It does, didn't realize that. Makes things much nicer :D. Didn't realize the avatar panel does this so just need to focus on names here.

TF2 should do this.. they only update player name on main menu when doing certain actions :x

I moved the lobby callback to DrawerPanel_Lobby so I could update the lobby owner name.
