add auto run applications

When the searched application becomes the only option remaining, the launcher automatically opens it.

Speeds up the overall user experience.

I think this behavior is confusing for user, even if set as optional from config.

Blue Line Console has several options that would appear after typing additional word, i.e. config will show the app config but confi will not, or ping nhiroki.net should apparently not be displayed by typing ping nhiroki.ne. Especially, for example, if confi matches only one app, once enabling the option, the user cannot just type to enter config anymore and even cannot turn the option off back.

For the reason above, this cannot be merged.
