Mentions updates in `bower list -h` command
    Basic usage tracking with insight

    The user is prompted with a question whether he would like to provide usage data
    on the first start, when run in interactive mode. The current implementation
    tracks calls to `install`, `info`, `search` and `uninstall` when run with at
    least one parameter.

    Fixes #260

Closes gh-796.
