* Restore prototypes of cmdbAbstractObject methods in which we added $sMode to preserve compatibility with existing extensions
* Rename cmdbAbstractObject::ENUM_OBJECT_MODE_XXX
* Add cmdbAbstractObject::ENUM_OBJECT_MODE_BULK_EDIT
* Refactor usage of $sDisplayMode in cmdbAbstractObject::DisplayModifyForm()
Done now before their as used too widely. We are most likely to allow dev. to use custom colors soon, so we want to avoid confusing / renaming then. (iTop extensions have been verified, none had to be migrated)
This way we ensure that a block always have the external resources from its ancestors as this will be necessary most of the time. From now on, the JS widget of the blocks will inherit from a common ancestor to factorize some mechanisms that are duplicates at many levels.
This can be disabled in a particular block by overloading the INCLUDE_ANCESTORS_DEFAULT_XXX_FILES constants in which case, only the external files of the block itself will be included.
