v0.0.6: Add a kill UI

It's simple, but at lest it allows you to confirm before killing and to
see an error message if it failed.

v0.0.5: Pick and kill processes

This release introduces the ability to pick a process and kill it.

Also, ftop has gotten even better at process naming.

v0.0.4: Implement process filtering

By command line, user name or PID.

This release also contains some command line parsing improvements.

v0.0.3: Deduplicate same-name processes

If you have multiple firefox processes running, starting with this
release they will be disambiguated as firefox[1], firefox[2], etc.

firefox[1] will be the oldest one. Suffixes are stable within one ftop
session.

v0.0.2: Add nativity as a sort criteria

This release adds another sort key. Processes which have recently
spawned many child processed will be shown higher in the list.

The point is that these processes are obviously active in some way, even
if they aren't using much CPU or memory.

v0.0.1: First release
