Added fancy new 'temperature gradients' feature.

Browse Source 
See docs for more details on 'temperature gradients', which can be
turned on with the -t switch on graphs.  Also improved parsing of
options with $execgraph and $execigraph, but may cause some breakage.

* Added fancy new 'temperature gradients' feature for graphs, via the -t
switch at the end of graph arguments.
2009-05-19
* Added inotify support to reload the config when modified automatically
on systems that support it
