Allow changing between xyplot,line,density for linear wiggle tracks and other small fixes

[cmdcolin]

Fixes #3051

• Allows toggling renderer type from the linearwiggledisplay->trackMenuItems if defaultRendering has a configSlot value (helps with e.g. snpcoverage which uses the linearwiggledisplay model but does not have multiple renderers)
• Moves some of the renderer-specific config slots to the individual renderers
• Fixes ability to change filled, displayCrossHatches from the config editor
