9959b84512 Initial commit of projextion integration.....dont get too happy cause its still not working yet...though it behaves nicely and doesnt kill qgis if it cant set up the projection environment properly. I believe the problem may be resolved by linking to libproj during build, because currently I get errors like this: 
ERROR 6: Failed to initialize PROJ.4 with `+proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs '.
The OGR Coordinate transformation for this layer could not be set

Ill try to track down the source of the problem following this commit.

c3ea8bcfa6 - rolled forward endian() changes in QgsDataProvider class hierarchy 
- rolled forward const-correctness changes from src directory

- in delimited text provider plug-in consolidated how data is parsed into a
  single function from three almost identical, but separate, functions; now
  uses QDataStream for building WKBPoint objects

- QgsDelimitedTextProvider::getFirstFeature() now works

f9820cd980 Debugging output to std::cerr was getting ignored, so changed to use 
qDebug().  Also now emit __FILE__ and __LINE__ so know exactly what debugging
statements are being executed.

48bca3c901 moved the responsability for not-commited features to qgsvectorlayer. Because of this, it is now possible to treat not-commited features like commited ones. Vectordataproviders now only need to implement 'addFeatures','deleteFeatures', 'supportsFeatureAddition' and 'supportsFeatureDeletion' if they support feature addition or deletion

99a6dba77b Implemented identify/selection using GEOS to return the proper features 
rather than any feature falling within the minumum bounding rectangle
(MBR). QGIS now required GEOS. This works with GEOS 2.x, needs to be
tested at GEOS 1.x

27d2c1bcab 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.

3cd56a824b 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

e059645ea2 - 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.

efa17e0ae5 - ran files through GNU indent to make it easier to read code 
- isValid() was always returning true when, in fact, occasionally the
  provider was not in a valid state

872cafa9d2 added intersect option to select to properly select features during select and identify operations. OGR does not support intersects so this is only implemented in the postgres provider
