Plot of state change numbers added to daily RDAHMM

A new plot function is added to the daily RDAHMM service. After doing RDAHMM analysis on all stations everyday, the service will draw a plot to display the variation of the number of stations with state changes through the whole time from 1994-1-1 to "today". We added new shell and gnuplot scripts to do this, and the service will generate a file containing the trace of the state change numbers as the input for these scripts.

On the daily RDAHMM portlet, a new tab is added to show this plot, as well as a link to the trace file, which contains the detailed information about each day's number of stations with state changes.
