Correct casing in AircraftStripView output

[n8rzz]

occasionally a string displayed in an aircraft strip will be lower case. This value should not be stored as uppercase, as it is only needed to be uppercase at render.

• update .text() outputs for aircraft route, destination, etc to include .toUpperCase()
• update any other outputs within AircraftStripView class that should be upper to use .toUpperCase()

Admittedly, this may not be the best solution. But it is an easy bandaid to implement until a better strategy can be found.
