Including dist/ in the .gitignore causes checked out tags to loose the binary files

  As recommended by the [bower README](https://github.com/bower/bower) "you should always check installed packages into source control..." This recommendation is largely because the user of a given library cannot guarantee the state of a repo after the day it is checked out. It could be deleted, moved flagged etc.

By including a .gitignore file with the dist/ directory in the release version of the code, any webapp (using git for source control) properly including a tagged version of backbone.paginator repo will loose the binary files on checkin. This can be a confusing bug since the code/tests may work durring development but will break for the next developer who pulls down the branch. The workaround is to re-build or re-check out and modify the .gitignore file in your local version of backbone.paginator which is not ideal as this provides an error prone upgrade path later.

In order to make releases usable "out of the box" I'd like to propose that we remove the dist/ directory from the .gitignore file. If it's feasable this fix should be backported to 0.8.1 and possibly further.
