#38 Default PDF file location should be same as project file location

[Brendan Simon]

The default location for generated PDF files (or any output file) should be the same location as the project file.

e.g. My project file is in path $(HOME)/aaa/bbb/ccc/ddd/eee/myproj.pod. When I load this and export to PDF (using File/Print/Preview/PDF) the default location to save is $(HOME) which forces me to navigate to the desired path.
