Set Rubyzip dependency to ~> 0.9.1

rubyzip 1.0.0 breaks compatibility, stick 0.9.x versions.

It seems Rubyzip 1.0.0 was released today, so after a bundle update it was using it for the roo dependency, However, it turns out that it breaks it:

cannot load such file -- zip/zipfilesystem
.rvm/gems/ruby-1.9.3-p448/gems/roo-1.10.3/lib/roo/generic_spreadsheet.rb:5:in `<top (required)>'
.rvm/gems/ruby-1.9.3-p448/gems/roo-1.10.3/lib/roo/excelx.rb:14:in `<top (required)>'

I see now im on quite an old version of roo, let me see if the newer version works with 1.0.0 anyway.

ok 1.12.1 has the issue as well
