- Changed cropper interface to a separate window rather than a dockpane
- enhanced some of the peak mapping UI - comboboxes now reflect state of database, rather than being controlled from cell controller.
- fixed plot labeling for color mapped plots
Missed file from last commit.

Fixed titla for colormapped plots, enhanced maps comboboxes on UI, implemented opening cell cropper as its own window instead of as a dockpane.
