termio.py:  Fixed a bug where the $LINES and $COLUMNS were not being set correctly on new terminals if you had dtach support enabled.
terminal.js:  A few minor tweaks to GateOne.Terminal.newTerminal() in order to make it do a better job detecting the correct EM dimensions of terminals before they're created.
gateone.js:  Added '✈noanimate' to the className attribute of the created temporary node inside of GateOne.Utils.getEmDimensions().
