Graphics context menu: spurious drag select; also delete hydrogens

[tic20@…]

The following bug report has been submitted:
Platform:        Linux-3.10.0-957.12.2.el7.x86_64-x86_64-with-centos-7.6.1810-Core
ChimeraX Version: 0.91 (2019-07-02)
Description
I really like the new (or new to me, at least!) ctrl-double-click mouse mode to bring up a context menu. A minor bug, though: if I ctrl-double-click on an atom, then (after releasing ctrl) click somewhere outside the drop-down menu to dismiss it, ChimeraX acts as if I've done a ctrl-left-drag and selects everything between the original double-click point and the final click.

Also, a suggestion: for the "delete atom(s)" options in the menu, it would probably make sense to automatically remove any hydrogens attached to the deleted heavy atoms.

Okay, the 'delete' command (which this context menu uses) now defaults to also deleting attached hydrogens (controlled by the 'attachedHyds' keyword).

Spurious drag selection also fixed.
