Title: Interpret command line PIDs as PIDs, not TIDs

The `-p` command line option takes TIDs, but arguably PIDs would be more useful. Here are some reasons why:

* Personally, I often want to look at a particular process, and much less often a particular thread.
* It can be confusing to specify a PID and see only the main thread, especially if the user is unaware there may exist more threads.
* Threads may come and go, so a list taken by the user before starting htop may not be accurate later.
