Line Edit: Support Selection

[frankmilliron]

Just a thought...
Allow double-clicking on the typed city name or OA-A to select all in Maps entry box.

Line Edit controls don't have support for selection. So it's not just a Maps thing.

Renamed the issue. The work needed would be:

• LineEditRecord replace caret_pos with sel_start and sel_end
• When sel_start == sel_end then show a blinking caret as today
• Otherwise, draw the selected range in inverse.
• Keyboard
  • Left/Right Arrow - if selection, collapse selection to start/end
  • OA/SA + Left/Right Arrow - if selection, collapse selection and move caret to start/end of string
  • Shift + Left/Right Arrow - move start/end of selection one character
  • OA/SA + Shift + Left/Right Arrow - move start/end of selection to start/end of string
  • Backspace, Ctrl+F, Ctrl+X - if selection, delete selection
  • Printable - if selection, replace selection / insert character
• Mouse
  • Double-click - select all
  • Mouse drag - select dragged range
  • Mouse click - collapse selection, place caret
• API
  • Option when initializing to select all or just caret
