Build also requires ruby1.9.1-dev

Frustratingly, the build has been failing but Jenkins has not
been noticing; 'gem install compass' fails with

/usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- mkmf (LoadError)

without ruby1.9.1-dev installed.

Fixes the OSD ordering in the last row when grouped by hostgroup.

The connectivity of hostgroup background is not proper.
Now, the position of last row osds are right aligned if it is an even row.
