Make the pdfattach utility more robust

Browse Source 
1. Handle filenames with spaces
2. Check if pdflatex and attachfile packages are installed before trying
to use them.
3. Use a more intuitive interface "pdfattach -o file.pdf file1.djvu
[file2.djvu]..." instead of forcing the user to specify "-i" option for
every input file.
