Improved: [DEPRECATION] Replace BigDecimal.ROUND_* by RoundingMode.*
(OFBIZ-9571)

No functional change.

We read at http://docs.oracle.com/javase/7/docs/api/java/math/BigDecimal.html : 
<<Using the integer fields in this class (such as ROUND_HALF_UP) to represent 
rounding mode is largely obsolete; the enumeration values of the RoundingMode 
enum, (such as RoundingMode.HALF_UP) should be used instead.>>

That's an easy global replacement. But it also needs to import the RoundingMode 
class. It was 26 files so I decided to rather clean all the imports in all files
 with the help of Eclipse.

This is a 1st step. I will need to closely look at 2 special class: UtilNumber
and Calculate.
