Flash driver improvements.

- Moved the Kinetis security check function to a new Flash_Kinetis base
  class, from which all Kinetis flash algos now derive.
- Improved security check to disallow an FOPT byte of 0x00.
- Removed specific Kinetis L-series flash algo classes in favour of a
  new Flash_klxx class, since the flash blob is the same for all current
  L-series devices.
- Changed Flash.programPage() to pass the length of the data array
  instead of a fixed page size, to allow to programming less than a full
  page, if the device supports it.

Remove whitespace
Fix python hang (on Windows) when an error occurred during the initial device init().

* Catch the exception and close down the interface, then reraise the exception so the program will not keep trying to use the failed board.

Fix a different python hang (on Windows) when an error occurred during the flash.init().

* No matter what, you have to call interface.close() to insure python.exe on Windows won't hang.
