[SDK] showinfo command doesn't work because of key misspelling

[AlphaDelta]

The showinfo <type> <title> <message> command is broken on Counter Strike: Source, as well as TF2 it seems.

The issue exists because the command sets a key "message" in a KeyValue object seen here:
https://github.com/ValveSoftware/source-sdk-2013/blob/0d8dceea4310fde5706b3ce1c70609d72a38efdf/mp/src/game/client/game_controls/vguitextwindow.cpp#L58

...which is then passed to CTextWindow::SetData

However the CTextWindow::SetData method expects a key of "msg", not "message", as seen here:
https://github.com/ValveSoftware/source-sdk-2013/blob/0d8dceea4310fde5706b3ce1c70609d72a38efdf/mp/src/game/client/game_controls/vguitextwindow.cpp#L388

The outcome of which is a VGUI 'info' panel being spawned with a title but no contents.

Also note that the key "cmd" is misspelt as "command" in the showinfo con command.
