Add possibility to set MyBatis properties via Spring context file

[GoogleCodeExporter]

What version of the MyBatis are you using?
mybatis-3.1.1
mybatis-spring-1.1.1

Please describe the problem.  Unit tests are best!
At the moment not all MyBatis properties could be set via Spring context file. 
We still need to have mybatis-config.xml. For example, mapUnderscoreToCamelCase.

What is the expected output? What do you see instead?
It would be good to have all configurations in one place only.

Can you provide stack trace, logs, error messages that are displayed?
No errors

Please provide any additional information below.
In the attachment you can find how we resolved this issue using Decorator 
pattern. This class depends on some external libraries (commons-lang, log4j) 
but it can be easy removed/replaced with java core classes.

Yes please, it will be nice to support mapUnderscoreToCamelCase and other 
properties.

Any way I could convince you guys to implement this? Setting this property is 
the only reason I've got mybatis configuration XML files, and I would love to 
do away with them.
