Fixed spelling mistakes and spatial reference

Replaced all references of "resultseach..." with "resultsearch..."
Changed the location of the spatial reference output in the XML file to be in the VectorLayer node rather than VectorData node. Now it displays in the formatted HTML. 
Could probably have changed the XSL...
Update catalogue.xsl

Added Projection information to the RasterData node and updated the VectorLayer node to reference "projection" rather than "spatial_reference"
Merge pull request #5 from mixedbredie/master

Updated gdalogr_catalogue.py with projection information
