Update kde4 eclasses

Add back support for doc handling (now via doc useflag)
Force kdeprefix only for kde-base things (others are going unprefixed to /usr) ->
Note for this: if user find that some application is pulling [-kdeprefix] kde uninstall/install of that app should help.
Rewritten slot handling with simpler code.
Added detection and alert system for finding what aplication break sth for /usr/share/config and /usr/share/kde4 and screw up perms.
Left for next time: "Support for stable live (live packages from stable branch [shiny huh]). :]"
