Resolving ExtractROI default behavior bug

Closes #1545 (closed)

This has to be done to integrate modification on UserValue behavior in PirvateDo(). Modified files are :

M       Modules/Applications/AppImageUtils/app/otbExtractROI.cxx
M       Modules/Wrappers/ApplicationEngine/include/otbWrapperApplication.h
M       Modules/Wrappers/ApplicationEngine/src/otbWrapperApplication.cxx
M       Modules/Wrappers/ApplicationEngine/include/otbWrapperNumericalParameter.h

New methods to get default value of numerical parameter has been implemented.

Nothing should have change about the application interface, except for GUI, start and size parameters are now disable if the mode is not standard.

A bug has been corrected in numerical parameter : when setting value out of allowed interval, the value is clamped.

Due to this latter modification a test has been modified :
