* modules/control/hotkeys.c: don't display OSD slider if stream is not seekable, when pressing 't' hotkey. 

                     input_ToggleES is removed.

* mediacontrol-core.c: update to the new control API
* configure.ac, Modules.am: (unfinished) build changes

Output PDF instead of PS

You will need 
 * xsltproc
 * the docbook XSL package

 follow the key-pressed scheme (I have removed thoses seeks).
 Someone to do the work ?
