[Tracker] tracker command line tools; pretty messy...

["Marcus Fritzsch" <fritschy googlemail com>]

As I now can search my ~/.purple chatlogs i tried it with
tracker-search from my loved zsh and found it being buggy. The same
holds for tracker-files and tracker-query. I am preparing a patch but
I am not sure if we want to commit this before release.

Another issue, the command line tools tracker-files and
tracker-meta-folder do not behave consistently regarding command line
options and --help.

Yet another one, I think a better name for tracker-meta-folder would
be tracker-directory-meta or something alike ;)

So, shall I fix the service issues? Someone wants to take care of the
command line behavior as that's not well known by myself.

Kind regards, Marcus
