Use macro to define kill-thing-at-point functions
Simplify km/join-next-line-with-space
Finally give ido-ubiquitous a try
Relocate recent files settings
Tweak `hippie-expand-try-functions-list'

Removed line and list completion functions, which are almost never what
I intend to complete. This should also take care of the clash with
paredit mode (since these multi-word expansions shouldn't occur
anymore), so I'm deleting `he-paredit-fix'.
