[PATCH RFC aiaiai 06/11] aiaiai: split sed project listing from list_projects

[Jacob Keller]

In order to allow other places such as hooks to list the projects,
seperate out the sed script into its own function. This enables less
code duplication if another script wants to list all projects in a
cfgfile.
