GetInfo function in DD

In the latest round of pushes to jamaica the function 
dynamicdata_user_getinfo has been removed. This is simply a wrapper 
function and folks using it should replace it with

DataObjectMaster::getInfo()

Apart from being consistent with the overall trend to replace function 
calls with static method calls where possible, in this case the function 
itself is becoming less important.

In most cases dynamicdata_user_getinfo is used to get the information 
required for a subsequent call to create a data object instance. This is 
especially true when you want to create an object by specifying its 
module and itemtype. However, since in jamaica you can simply specify 
the name of the object to create it, the module-cum-itemtype method is 
becoming less important (and will eventually be dropped). Rather, the 
easiest way to create an object is

DataObjectMaster::getObject(array('name' => 'foo'))

The dynamicdata_user_getinfo function returns an array of information 
about the object. It is really just the information contained in the 
object's entry in the dynamicdata_objects table. If one really needs 
this sort of information the recommended way is to get it from the 
object directly.
