Support catkin locate --this

[beetleskin]

For various bash commands, it would be nice to locate the package of the current working directory. My current workaround is

catkin locate `catkin list --this -u`

but the missing --this always felt wrong, since most other verbs support it.

A PR to add this functionality would be welcome!

I could give it a shot, would you point me to the right piece of code to put this in?

Note, this feature was introduced in 09e2b12, and should work on any version >=0.4.0

[beetleskin]

That's not true: the commit added catkin list --this, not catkin locate --this. I'm asking for the latter.

[jarvisschultz]

Doh.... sorry. Totally misread the original comment

[jarvisschultz]

Felt bad I gave dumb advice, so just submitted a PR.

[beetleskin]

haha, nice, thanks :)

This was fixed in #605.
