#10 Closing Json Viewer also closes Doc Switcher

[GreenMoose]

Repro:

1. Go to Settings->Preferences->General and check "Show" on "Document List Panel"
2. Notice you get a list of open files on the left with title "Doc Switcher"
3. Select Plugins->JSTool->Json Viewer
4. Note that the json viewer replaces "Doc Switcher"
5. Close json viewer via the x button at top right, "Doc Switcher" is hidden.
6. o to Settings->Preferences->Generalm, notice "Show" on document list panel is still checked.

Expected:
When closing json viewer my "Doc Switcher" should remain visible

Actual:
When closing json viewer the "Doc switcher" unexpectedly also closes.
