- new option: colorbar_position ['bottom', 'right', 'upper', 'left'] lets you choose where the color bar should appear for m x n plots (not for singlerow or singlecolumn plots). Works with basemap-plot.py and im-plot.py
- renamed and improved option: inner_title -> inner_titles 'a),$\gamma=3$,my text' which now takes a string converted into a comma-separated list for more precise inner titles.
