[IMP] select wkhtml2pdf between x64 & x32 versions

- Automatically choose between wkhtml2pdf x64 and x32 versions,
   according of host architecture.
 - Replaced "dpkg -i" with "gdebi --n", in order to have installed
   all wkhtml2pdf dependencies automatically, if any of them is missing
   from the system.
 - Make shortcuts in /usr/bin directory, instead of copying actual binary
   files that are part of installed wkthml2pdf package.
 - Added .gitignore in order to prevent garbage file upload to the
   repository.
