[dga711]

Fixes and preperation for the 0.4.0 release

TODO
Thinks we don't fix here we should create issues for after release

• Changelog
• AUDIO: Seatbelt announcement CHIME not playing anymore @J-Hoskin
• LEGS: index problems when departure is loaded, look at FPLN fix cannot always reproduce
• FPLN: Set arr. Entering airway would result in the exit waypoint missing. After EXEC its there https://streamable.com/0zi4gg
• FPLN: direct waypoints show connected airway even if it is direct, see _GetAllRows Nothing we can do now
• FPLN: When is TO on page 1 magenta? always? @K20017 / Manual says that active leg is magenta?
• AUDIO: Air fan works without power
• FPLN: When an airway doesn't fit the intersection the error is "NOT IN DATABASE", which is not correct
• Test and pull in @J-Hoskin 's mfd changes if possible
• LEGS: can we make direct to IAF work again?- [x] LEGS: show decimal on all waypoints <100nm distance
• ARR: After deselecting arrival "Working..." stays
• FPLN: I feel like adding airways as first waypoint after departure is inconsistent. Needs more testing.
• Change version in about page
• FPLN: make airways work
• FPLN: always offer an empty line for "add"
• FPLN: only show airway entry/exit (next release?)
• FPLN: Sometimes when you enter a VIA it doesnt show up. But you can then enter waypoint and it works
• FPLN: offer SelectWpt on inserting airway when TO not clear
• FPLN: doesn't show VIA/TO on page 2+
• FPLN: Delete on TO page 1 puts fix CLRIC in it
• FPLN: delete doesnt work when departure active (index problems) / my quickfix seems to not work
• DEP/ARR: Merged PR by @tscharlii: Fix header color, update changelog with credits, fix working message
• "Working..." message doesnt show, even though it is called (basically everywhere)
• Thrust and Fuel Mgmt changes
• LEGS: Indexes for modifications seem to be wrong when approach is loaded
  -> while testing it seemed fine. still keep an eye open for it
• LEGS: show runway where possible
• LEGS: dont let the pilot move around approach fixes
• Improve waypoint loading performance in FMC
• VORs always display twice in FMC waypoint loader because they are both a VOR and Intersection type waypoint
