Subject: Add magic "js " prefix to runDialog to run arbitrary JavaScript
X-Git-Tag: archive/raspbian/50.5-1+rpi1~1^2~1013^2^2~11213

Add magic "js " prefix to runDialog to run arbitrary JavaScript

This is useful for debugging things; e.g. you can "js Meta.quit(0)"
to exit the WM, "js Shell.Global.get().<whatever>..." etc.
