Feature: Dropout forms for Flight Data and Flight Planner

[LEGIONBOSS]

This feature makes it possible to drop out a various elements from the Flight Data screen into seperate windows.

Fetaures include:

• Extendable dropout form management (new controls can be added as needed)
• Under the HUD Tabs:
  • Dropout form functionality on a double click on the tab header (and off-session saving of it's position, size and dropped-out state)
  • Removal of "undock" action from Quick tab (has been replaced by the double click method)
  • Indexed in-order insertion of tabs (when their dropout forms are closed)
• Flight Planner: Dropout form functionality with the same off-session saving and loading
  • (the dropout window closes if the user swithes to the Flight Planner window using menu strip at the top)
• HUD: Off-session saving and loading of positoon, size and dropped-out state
• Connection Stats Window: Off-session saving and loading of positoon, size and dropped-out state

All saving and loading is handled using the already existing functions from the ControlHelpers and Settings classes.

This is a very helpful change for multi-monitor GCS systems. We started to use it a while ago.. (Notice, LegionBoss is working in my team :) )
