Changed the indent on the bar - maybe need to add pixel specification config option for this
Grouped styles implemented, lots of the styling and feature config code abstracted into subs so are common between RENDER_simple and RENDER_grouped.
Group style now takes colour and height from the default feature style if there is no other style to use.
Added between-species hyperlink for synteny tracks (cytoview)
Changed to jump from synteny block to CytoView rather than ContigView. CytoView seems more appropriate as blocks are often too large to be viewed in ContigView
group style now defaults to feature style
fixed a bug when the first summary feature got lost
do not try to display translations that do not have DB ID
Added no_anchor option to stylesheet to turn off display of vertical bar anchor.  This gives a 'classic' arrow.
new group zmenu, and vertical fix for labels
Fixed the zoom and jump links by changing slice->name call to slice->seq_region_name
added tagged snp track
Prevents "ghost" features with start/stop of 0 being drawn on image and breaking imagemap
Changed bar_indent to be more useful at small symbol heights
changed id in group menus to id, rather than label
draw features in black if they are of unknown type
Updated group menus
homepage config option for DAS sources to set track 'more info' URL
