Enable JPEG Huffman table optimisation

Enable Huffman table optimisation for JPEG tiles to shave a bit more off
the file size.
Removed Oracle GDAL plugins

Removed some Oracle data format plugins for GDAL that were causing
unwanted loading errors in the console.
Tidied up preference key and checkbox

Moved  Last Input Directory preference key name into a static String
INPUT_DIR_KEY.
Disable bilinearOverviewsCheck when overviewsCheck is deselected.
Close image files when finished

Added a try finally to ensure that the image files are closed when they
have been finished.
Otherwise the program keeps them locked until it is closed.
Added GDAL data and driver path env variables

Allow setting the GDAL data and driver path via environment variables so
that program can be debugged from inside of Eclipse.
Added temporary fix for bug in GDAL v1.8 & 1.9

There is a newly discovered bug in CoordinateTransformation in GDAL
earlier than v2.0.

It can crash if there is no transform between the two projections found.

After v2.0 this code should be replaced with the new
osr.CreateCoordinateTransformation function.
