Fixed catalog plotting options.

[pabloitu]

The magnitude ticks defined as default in catalog.plot() were spurious, and created problems if the magnitude range of the catalog was not in a similar range. The default now for magnitude legend elements are numpy.linspace(min(mw_range), max(mw_range), 4). Rounding of the magnitude is to one decimal, but only in the legend text. Raise a warning, if the passed magnitude_ticks are outside of the catalog mw range.
