RFR: 8328400: Minor Cleanup

[Andy Goryachev]

- PrismTextLayout:325 misspelled 'sliptCaretOffset'
- DatePicker System.err.println L 125, 139, 172, 256
- SpinnerTest.java L 1588, 1609 -> loses/losing (also in MenuBarSkin, DatePickerTest, FocusTest, and a few more)
- Labeled:821 obsolete comment

Some more typos:
- occuring -> occurring (e.g. CellBehaviourBase)
- ButtonTest - conextMenuShouldntShowOnAction -> context...
- ControlResources - translateable -> translatable
- DateCellSkin - Pirvate -> Private
- totaly -> totally (e.g. LineChart)
- MenuItem - programatically -> programmatically
- Tooltip - invaildated -> invalidated

(thank you @Maran23 )
