- properly namespace the input methods. fixes symbols clashes at run-time

  with names like 'Keyboard' or 'KeyboardConfig' . the qcom interface
  objects are in an anonymous namespace now and the actual keyboard
  implementations are in Dvorak, JumpX, etc. namespaces.

What's left is to solve the symbol clashes of the multiply compiled
pickboard classes. I'll leave that one (as part of the patch posted
yesterday) for another day for review. This part (namespacing) sounds like
a safe bet to me though, so comitting now. (got no comments anyway)

  * make a kor/eng swaping key
  *
  * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * 
  *
  * how korean input works
  *
  * all following chars means unicode char value and are in hex
  *
  * ÃÊÀ½ = schar (start char)
  * ÁßÀ½ = mchar (middle char)
  * ³¡À½ = echar (end char)
  *
  * there are 19 schars. unicode position is at 1100 - 1112
  * there are 21 mchars. unicode position is at 1161 - 1175
  * there are 27 echars. unicode position is at 11a8 - 11c2
  *
  * the map with everything combined is at ac00 - d7a3
  *
  * to find a combination of schar + mchar in the map, lookup
