[FIXED] Game on mobiles

[Unknown98]

As a temp solution until I actually make a mobile theme for the game what I've done is remove the miles column from the fleet overview page. This should make it all fit on the screen now. Mileage has been moved to the aircraft detail page. Mileage doesn't matter much anyway, when maintenance is implemented it will depend mostly on cycles and hours, not necessarily miles. So moving the mileage to the detail page shouldn't be an inconvenience.
