ViewDockX save broken

[pett]

The following bug report has been submitted:
Platform:        Darwin-18.7.0-x86_64-i386-64bit
ChimeraX Version: 1.0rc202005190042 (2020-05-19 00:42:41 UTC)
Description
Trying to "Save" in ViewDockX.  It seems that the 'saved_output' attribute of OutputCache is only set when the underlying stream is closed, but is accessed while the stream is still open.  Noticed this as I was updating SaveDialog to not use old code, so you may need to pull latest changes.

Fixed in 1baab4c05.

Some code got indented too far and ended up inside the "with" statement instead of outside.
