Patch Friday: Second Patch release for 2.9

Jalview 2.9.0b2 fixes a Desktop bug where group associated consensus and conservation annotation rows are duplicated when an alignment is partitioned by clicking on the tree viewer.

This version of Jalview is also the first to be provided as ‘timestamped’ signed jars. What this means is that Jalview 2.9.0b2 will always be allowed to run on systems that support Java, even after our Certum code signing certificate is no longer valid. Thanks to for providing a public timestamp server !
