Improved support for detecting missing dependencies:

- Added libpaper-dev package checking.

- Previously, SDL_Pango's bug forced Tux Paint to include a customized
  version of SDL_Pango.h in its distribution, so we couldn't tell if
  SDL_Pango was installed in the system by including SDL_Pango.h.  We made
  a new workaround for SDL_Pango's bug that does not require Tux Paint to
  include SDL_Pango.h, so now we can check for SDL_Pango installation.

- Makefile now includes a check for gettext installation and will not
  fail when attempting to generate .mo files or install .mo files.  Instead,
  Makefile will now display a warning and skip the .mo file generation and
  installation steps.

Many thanks to Arunodai Vudem for the patches.
