added better coloring for strand matches

Fixes #412

@childers If you have a chance to look at this and let us know if similar matches for .cigarE / .cigar? would be helpful.

This is a pretty simple fix. You can also issue a separate PR / patch.

@deepakunni3 I think this is ready for review. Not sure what the history of why this wasn't done in the first place (in WA1) as it was pretty easy.

BWT, does this fix #1044 as well?

I wanted this fix for #1619 (to check errors).

@nathandunn It would be awesome if the color of the reads matched JBrowse/Alignment track.

Here is an image that shows the comparison of WebApollo/DraggableAlignments vs JBrowse/Alignment:

color for forward strand aligned reads - #EC8B8B
color reverse strand aligned reads - #898FD8

Also, the span between two paired end reads should be a lighter shade,
