Castle Game Engine: Fixes to 3rd-person navigation, UI outline and groups, LSP range check error

From Castle Game Engine: link to original post

Fixes to third person navigation component and example:

• Fixed the design-time behavior — the existence of TCastleThirdPersonNavigation should not affect behavior of camera at design-time.

• TCastleThirdPersonNavigation.DistanceToAvatarTarget secured in case it is zero, previously it got us into weird transformation bug.

• TCastleNavigation.ZoomEnabled behavior on TCastleThirdPersonNavigation fixed

• Accidental playing of walking animation (even if you don’t hold “W” key) fixed.

Fixes to UI:

• Switching to TCastleUserInterfaceFont.Outline = 0 fixed.

• Updating group when child TCastleUserInterfaceFont.FontSize changes fixed.

• TCastleUserInterfaceFont.Outline changes now row height of controls like edit or label.

LSP server:

• Important fix to avoid crash due to range check error.

• Tested with VSCodium and officially documented on VS Code page.
