Ceph Dash Versions Save

Since I've got no negative reponses, I release the next stable version of ceph-dash (v0.8)

Changes in this release:

• new configuration options for adding grapghs from graphite
• Included Javascript Flot library for drwaing graphs
• Sections in ceph-dash can now be collapsed to show only what you want to see

I decided that it would be useful to use githubs release feature, to mark stable points in the development.

Changes in this release:

• added ceph-dash specific css file
• cleanup in javascript file
• sections are now collapsable, so you can concentrate on what is important for you
