Saving window size instead of buffer size to allow free window size and therefore not interfere with automatic window arrangement
Removing ResizeWindow to size window freely
Enabling WS_MAXIMIZEBOX because it's a requirement for Windows 7 automatic window arrangement
Changing CreateNewTab so that it doesn't undo Windows 7 automatic window arrangement
Changing tab title to console title (if it's not null) or 'current folder: command'
Changing the command separator from - to : because a file or folder name can contain - (so that it's less clear if the delimiter is part of a file or folder name or not)
Removing m_strTitle, SetTitle, OnEditRenameTab (to reduce complexity) because they have limited use
