Colormap UI

Based on a discussion between myself, Ken, Utkarsh and Amy, the new colormap dialog should look kinda like this:
Basics
- Each control point on the colormap has an index and a scalar value. This scalar value is absolute, it is not normalized in any way.
- The user can adjust the position (scalar value) of internal control points by either entering the scalar value (clamped to end values) or moving the control points with a mouse
- The user can add points by clicking on the colormap widget
- The user can change the range (min/max) of the colormap by selecting one of the end points and changing it's scalar value. This will not change the scalar value of the other control points
- If "Automatically adjust to fit scalar range" is checked, the scalar values of all control points will be adjusted every time the range of the corresponding array changes
- If "Automatically adjust to fit scalar range" is not checked, the color map is "locked" and does not change automatically
- To adjust all points on the colormap, the user can click "Adjust Colormap" to get:
On this dialog:
- Pressing "Rescaled based on current" will adjust all control points to the current scalar range of the associated array
- Pressing "Rescale to" will adjust all control points to the range specified with min/max values.
