Title: Adds a refresh button to the "cylc graph" viewer.

And removes automatic load of modified ```suite.rc``` file.

The automatic load-on-change functionality caused dire problems if a non-validating suite was saved with a graph window open.

The new Refresh button can also be used to cycle through the possible graphviz layouts for the same graph structure.
