my-toggles: some simple toggles.
my-toggles: add C-x t u - toggle undo keeping

This is useful for large log files.
my-c-mode.el: add linux-tabs-style

The default "linux" style doesn't set-up tabs as you expect. This
derives a new mode which does.
init.el: remove global white space key (see my-toggles)
my-circe.el: use password helper function
my-toggles: add "w"hitespace toggle
my-package: remove ack-and-a-half

I'll use ag from now on.
