Followup-For: Bug #839133

Dear All,

Due to the codemirror editor gets read-only. Here is a workaround
to use text editor with osc command to edit Meta config and Project
config for the project.

Steps for the workaround:

1) install osc
 $ sudo apt-get install osc
2) Edit your project config:
 $ osc meta -e prjconf <project>
3) Edit your meta config:
 $ osc meta -e prj <project>

Best regards,

-Andrew
