Replace Tracker add-on filename shortcuts with attributes

[leavengood]

Currently the shortcuts used for Tracker add-ons are "configured" by appending them to the end of the filename (LikeThis-T). This is not ideal.

A better solution might be to use attributes, as well as a simple Tracker Preferences pane to edit these attribute-based shortcuts.

This was originally discussed on the haiku-commits mailing list starting here:

I think it's a good idea to put the shortcut into an editable attribute. I'm not sure it's necessary to put the editing into Tracker Preferences, though. Just make sure the shortcut attribute is displayed in the */add-ons/tracker/ folders.
Maybe an "Edit Shortcuts..." item in the Tracker Add-Ons submenu that opens the target folders of all displayed add-ons? Similar to the "Edit Templates..." of the "New..." feature.

IOW this will not allow for customization. And not only in a multi user environment, but also in the package manager environment we'll soon have.
