Debian "enhances" tag should contain only those WMs which are definitely enhanced by alttab

[sagb]

WM should have:

1. stacking or fullscreen behaviour by default
2. no built-in alt-tab feature or "inconvenient" one. Openbox-like (vertical) or our-style (horizontal) GUI are considered "convenient".

Definite candidates for "enhances" tag are marked bold.
