Allow multiple commands in debug console

[mister-game]

Like Linux, allow multiple commands to be entered into debug console, separated by a semicolon,
e.g.
setaccount "DTrJPBR6GPyD5rUcUyPHsYNkYUniDSMJn5" "xxxxxxcont401";
setaccount "DPgZJ8Ps1b54tCs1VXuwLhVV4LChosFTUy" "xxxxxxcont402";
setaccount "DSe8YxR1g3bYSFGEC1fAgAW7rxwjrBsUe7" "xxxxxxcont403";
setaccount "D6Q1uHtsDFSX2bLg2Ro9BuWofDc3z8hdyp" "xxxxxxcont404";

This would save a lot of back and forth,copying and pasting.
