Histogram axis ranges

[pat-s]

Are hardcoded currently.

DataExplorer/R/plot_histogram.r

Lines 64 to 65 in f539a68

	scale_x_continuous(labels = comma) +
	scale_y_continuous(labels = comma) +

This leads to undesired behavior in histograms for variables with only 1 digit.

Given the fact that the ggplot objects are not returned, its not possible to change it. Looking forward to v0.7 :)

Removed almost all hard-coded scales from all plot functions.
