implement possibility to select the resolution even in dtlogin mode so

that ThinLinc, rdp, vnc, etc. connections can be explicitly opened in
window mode instead of forcing full-screen for all dtlogin driven
connections. Now a user can choose to open the connection in a window
instead so that within a windows thinclient environment users can have
more flexibility on how to open remote connections.
