Adjust number of depth scale ticks depending on data scale so even at tiny scales there are several ticks; scroll based on data scale instead of in 1m increments; replaced colorList with a dictionary in order to refer to colors by meaningful names instead of arbitrary numbers; fixed control ID collision in Color Set dialog: the "Overlapped" colors' IDs overrode the first nine standard colors, so they never updated; on startup, always expand Root element in Data Manager; apparently I also called Eclipse's "Format" command at some point, thus all the spacing-only one-line changes.
Allow more than two points of decimal precision in data
Renamed ScrollOpt and ScrollBackOpt to isSecondScroll and isSecondScrollBackup; addressed fallout from move to wx2.9 (rename wx.Color -> wx.Colour, work around new windowing issues, make GridSizers sufficiently large to hold all components)
