Removed trailing witespaces and added blank lines between functions
Change default filename and title

The previous defaults where just placeholders. With this change both will
use the current folder name.
Remove "non inline" images option

It's been more than two years since I touched this code, so I don't
remember what I was thinking, but using non inline images is pointless for
this tool. Non inline images are better when you can use one image
multiple times in the same PDF, but that simply doesn't happen in this
tool, ever, so there is no size advantage.

As for inline images being problematic, it's not a problem with inlining
them, but with poorly implemented viewers. Most viewers don't have a
problem with this, and since it's the viewer fault, whoever finds trouble
with this should fix it or look for a better viewer.
Remove unnecesary functions

PDF text compression is only of any use when text is stored in the PDF
file. Since this tool only stores images, this option is useless.

Rotation is out of the scope of this tool. If the images need any kind of
processing, this is the wrong tool to do that. K.I.S.S.
Remove resizing option

Removal of another image processing option. There are a lot of tools to
manipulate images out there. If they must be of an specific size, proccess
them beforehand.

This fixes a bug in the image manipulation where the script was outputing
bitmaps to the PDF instead of JPEG files, producing REALLY BIG files.

A quick test produces a 1,5MB PDF where before this change would produce
a 22MB one, showing that K.I.S.S. is a good principle.
Removed part of the debug output

Guppy's hpy makes this script REALLY slow, and the provided information is
of no use for a script this simple.
Updated copyright line and bumped version to 2.0

With this, the script is so simple there is little to be improved in
the future, and it may as well remain as is for an even longer time, so
bump the version to 2.0.

Also remove an unnecesary import.
