implemented and tested QgsShapeFileProvider::getNextFeature(list<int>). This speeds up rendering of graduated symbol layers a lot (especially if there is much attribute data). However, for the commit, the old getNextFeature(bool) has been enabled again, because getNextFeature(list) has to be implemented in all data providers to not break the other providers.

added a method getNextFeature(std::list<int>&) to the dataprovider classes (but didn't program it yet). The idea is, that besides copying no attributes (getNextFeature(false)) or all attributes (getNextFeature(true)), it should be possible to copy only the attributes with indexes contained in the passed list. This should improve the rendering efficiency of graduated renderers. I plan to implement this method for the shapefileprovider and make some efficiency tests. For the other data provider, it would be nice to have some help, because i am not very familiar with e.g. the postgresprovider, the delimited text provider or the grass provider

- plugged memory leak in QgsShapeFileProvider::getFirstFeature() whereby the
...
OGRFeature wasn't getting destroyed
- made getFirstFeature() a little more robust with regards to handling memory
related errors
- implementation files should include their own headers first, so moved its
#include accordingly to top; the meant creating class forward declarations
in header file.

- isValid() was always returning true when, in fact, occasionally the
provider was not in a valid state
