Installing gem to vendor/bundle causes graphical git client to crash

set bundler to install into vendor/bundle and put it up into git. when you download it to windows window will delete the files. Git client (graphical) crashes. Using sourcetree it shows the files are deleted. however, it wouldn’t allow a commit because it can’t find the files. It /really/ seems like a git client bug to me, they should be able to deal with the missing files.

This is because in the docs/ there are filenames with colins -- an illegal character on windows.

We could update the hydra.gemspec to exclude docs/ from the packaged gem, this would likely solve the issue.
