CLI Plugin: List items matching a pattern

[ohinckel]

Just an idea: I have a lot of items and the la command output is really large and i need to search for the items I currently want to see, which is not handy.

I implemented a item matching mechanism using the sh.match_item() function instead of sh.return_item() for:

• ls - will list all matching items, e.g. ls groundfloor.*.light
• update, up - will update all matching items to value, e.g. up groundfloor.*.light = True

Maybe we should use a new keyword for the update command, since this actually change values and it could happen that someone change a lot of values accidentally by typing a * somewhere in the path.

Since every time the match_item() function is used, this patch will slightly slow down the mentioned commands. I did not a benchmark on this, since the CLI interface is mainly used for developers, debugging or testing purpose.

The documentation update is not included in this patch - I can do this if we want to support this feature.
