README note about the availability of mini_exiftool_vendored

[wilg]

Hi Jan,

Thanks so much for integrating my save! method into master. The 1.6.0 release fixed all the needs I had for my own branch, except for my use case I felt it would be great to have Exiftool included in the gem.

That's probably not a good fit for what you want, so I've created a meta-gem (http://github.com/supapuerco/mini_exiftool_vendored) that does nothing but automatically set the command= to the bundled version. It has a gem dependency for mini_exiftool, so there's no duplication of code or anything.

I figured some other people might find that useful, so I've added a note about it to the readme.

Thanks,
Wil

Hint in README inserted. When will we see Perl bundled? ;-)
