$fields argument for views_service.get

This is actually a re-introduction of an argument which was present in older versions of views_service, simply because the data which is returned at the moment by Views 2 is quite a mess:
if the row plugin is set to 'fields' -> results in extra long property names (this is a views 2 module issue), and eg. an imagefield cck data is not complete (no file path), which render this data useless
if the row plugin is set to 'node' -> results in all the nodes data, which is overkill if only eg. the image of a node is needed

Ideal would be that the 'fields' row plugin would return the node struct/object which only contains the fields set in the view (with the proper data, and actual property names), but from a first glance at Views I realize this is quite complex to achieve, even more as there is the possibility to add other fields then type Node/Content (eg. Global/Taxonomy/User…), which would require additional data preparation in the views service module.

In short, re-introducing the fields argument is probably a temporary solution till an ideal solution is available, but at least it is not a loss of a feature which was available before.
