Alignments2 - Highlight this match

[keiranmraine]

The right click context menu give a 'highlight this match' option. This suggests that it would highlight the mate read but it highlights the current read.

Ideally this would highlight both ends of the read pair.

@keiranmraine if we do #521, would we need this? We're thinking of closing this in favor of doing #521

@rbuels , I concur with choosing #521 over this.
