Description:
It seems that the thumbnail graphs do not always update when switching between servers in the tree nav. I suspect this is an issue with caching, either caching in the file system or in the browser. This was noted in firefox.

How to repeat:
Make sure you are running merlin with agents monitoring different machines (so that the graphs are likely to be perceptibly different).
Select one server and note the thumbnail graphs.
Select a different server and note the thumbnail graphs appear to be the same.

Suggested fix:
Append an md5 of the group or server name to the thumbnail URL to make the files appear different to the browser (assuming it is a browser cache issue).

Updated to use unique urls by appending md5 of exploded list of servers in selection as appended get param. Patch queued.
