Copyright-holder and year information is extracted from git log.
git history begins in 2005. So (C) from 1998..2005 is lost. Also some
(C) assignment of commits where the committer didn't use --author.
Removed the term "Lua", because users were turned off by something they didn't understand.
A special-case Lua script ("Shortcut") allows the user to select an arbitrary Action.
The "Shortcut" script is selected by default, and in this case there is no "Type" or "Author" displayed.
Action-Buttons may still trigger Lua scripts, as a secondary function.
