org-plot.el: add utility functions for range,ticks

:ymax :xmin :xmax, as well as :min and :max as aliases to the y{min,max}
options. The :ticks option is also added, for specifying how many ticks
should be used.
(org--plot/values-stats, org--plot/sensible-tick-num,
org--plot/nice-frequency-pick, org--plot/merge-alists,
org--plot/item-frequencies, org--plot/prime-factors): New utility
functions added to allow for somewhat sensible determination of a :ticks
value when none is provided. This turns out to be harder than expected,
and so a number of functions are used to attempt to do so. The essence
of the method used, is to round values and find their prime
decompositions. From this we try to select the most common components
to give a reasonable step size. We also add a 'ticks' parameter for
manually setting the number of ticks, and (y)min/max parameters
similarly.

If I understand you correctly, then what we want to expose is the
"timefmt" that is put into the data file and then passed to gnuplot.
The following patch is a complete one against current which adds this
(it works for me, at least), and documents the new +PLOT option
behavior.
The one thing I'm not sure about is my method of passing the timefmt
parameter all the way into the temp file creation function. I made a
buffer-local variable there to do it. That seemed the least intrusive
way to accomplish this, but it seemed like poor practice. Thoughts?
You know, I really ought to allow a person to customize this variable (I
mean, using customize).

The car is the type name, and the property :plot-func must be
|

set. The value of :plot-func is a lambda which yields plot-lines

\(a list of strings) as the cdr.

All lambda functions have the parameters of
|
|
|

`org-plot/gnuplot-script' and PLOT-STR passed to them. i.e. they

are called with the following signature: (TABLE DATA-FILE
