GM_openInTab sometimes opens tabs in wrong window

STR:

1. Install script https://gist.github.com/Y0ba/a2b623d4f30bb814d192
2. Open https://github.com/greasemonkey/greasemonkey
3. Drag tab down, so it creates a new window
4. Click link

GM_openInTab opens new tab in the first window, but should open after the tab where it was called.

https://github.com/Ventero/greasemonkey/tree/issue1758 contains a fix for this issue, as well as a semi-related commit (which stops unnecessarily passing a chrome window to GM_rmc).

Strictly speaking, something similar has to be done for the firebug console, if one was detected during load. However, as Firebug creates a new console instance when the content window is moved, this would require checking for a new Firebug console during every call to console.{log,warn,...}, so I'm not sure if this should be done.
