Enhancement:
============
Option for BULK MODE SCAN from NATIVE APPLICATION is added. Check ZXing Test application for sample use. See button "Bulk Scan Anything".

Minor Note:
-----------
Many files have very simple changes due to removal of java 1.7 features like <>, switch on string etc. It is because i am using eclipse and by default Android doesn't support java 1.6
