new auth capability 'logout'

This patch implements what Adrian's patch "Hide logout button if auth
backend cannot logout" intended to do.

The 'logoff' capability was used to decide if a special method called
$auth->logOff() should be called when the user logs out, not if the
backend supports logouts at all. This was a superflous capability since
an empty logOff() method is implemented in the base class anyway - it
doesn't hurt to always call the method.

The 'logoff' capability is now deprecated. Backends who want to do
actions on logout simply need to overwrite logOff().

A new capability 'logout' was added which defaults to true. Backends
that can't logoff the user (eg. because they use some automatic
login/logoff mechanism) can set this to false.

Probably makes sense to add a 'login' capability as well...

Refactor action links and buttons

Behavioural changes:
* buttons
* no 'do=show' but clean URLs (show and back buttons)
* the alias 'subscription' for subscribe buttons is now available
* links
* draft link has class 'draft', not 'edit'
* revisions link has class 'revs', not 'revisions'
* both
* 'revision' is added as an alias for 'history'

These changes were mainly introduced to reduce the differences between
links and buttons.

Omit do=show from URLs

It looks like when there is no "do=" parameter to doku.php, "show" is
assumed. When clean URLs are used (via mod_rewrite), regular
page-to-page links hence just link to "pagename". However, if you "Show
pagesource", then "Show page", the browser is sent back to
"pagename?do=show" instead of just "pagename". This seems like a "less
clean" URL to me.

So, the attached patch removes "do=show" from URLs in this case, so
cleaner URLs are used.
