Title: Fix bin directory for heroku + update to 2.7

I couldn't get the kindlegen gem work on heroku, it always complained of having not permissions to write to /usr/local/bin or something similar. I think that the ```Dir::pwd.include?( 'gems' ) && FileTest.directory?( bindir )```switch didn't worked, so I rewrote this part. What do you think?
