Giddy is the prophecied GUI pickaxe frontend for Git

Pickaxe is perhaps a not-so-well-known mechanism in Git to grep commit changes
for strings, front-ended by git log -S. This means that

        git log -S'panic()'

will show you all commits that introduce or remove the string 'panic()' from
the source. This is a more flexible alternative to git blame, which does
pretty much the same thing, but only on line level.

This tool will let you select the strings in a Gtk GUI view of the file and
follow the evolution of code blocks you are after.


Please bear in mind that this has been written in 24+3 hours by a tired
hacker who coded in GTK for pretty much the first time. That's my excuse
why it looks like crap, yes. ;-)
3000ft design overview:

main -> layouts GTK
     -> Giddy::Controller
		<-> Giddy::Toolbar
		<-> Giddy::TreeBrowser
		<-> Giddy::CommitBrowser
		<-> Giddy::FilesPanel
			-> Giddy::FileTab
				-> Giddy::FileViewer | Giddy::CommitViewer
				-> Giddy::DiffViewer

(Giddy::FileViewer and Giddy::DiffViewer have common ancestor
Giddy::PickaxableViewer.)

(Interaction between the objects is controlled by Giddy::Controller.
Thus, it should be possible to take e.g. Giddy::FileViewer and use
it standalone from the rest.)
