Revise commit 4c34f5980bddcdc84b10cb3bcbb96b365b9d471e (Bug 767): TAB, BS and CR/ENTER are printable for NEWT KeyEvent and font handling. Fix regression.

- Original behavior was treating CR/ENTER them as printable, lets keep it this way.
- KeyEvent: Query these 3 whitespaces upfront, no need to incl. them in 'nonPrintableKeys'.

- Fix regression: Native VK_ENTER was not change in commit 4c34f5980bddcdc84b10cb3bcbb96b365b9d471e.
