Reduce initial right panel width

[Don-Isdale]

This sub-issue is part of #443.

---

The Initial width of the right panel has increased in recent releases, which creates more space for the results of the VCF Genotype Search, but less for the axes; in the simple case users will be viewing just 1 axis, but it is felt that the initial right panel width should be reduced.
