Menu Problems and My Aircraft Layout

Added all the options that are needed in the Menu
but there seems to be a problem with the working
of the Drop Down Menu. Need to look into that.
Alongwith that, i have also added the codes for the
MyAircraft Page that will show a table of all the
aircrafts to the system/user.
Cleaned the HTML File and also added some classes
to CSS file.
