Add open_plugin to core

open_plugin allows arbitrary plugins to be called
in hotkey and start screen

replaces PictureFlow Integration
shortcuts menu plays plugins now too

rather than store paths and parameters in the settings
that reside in memory instead entries in a file are searched by hash.
after all, the plugin has to be loaded from disk anyways

----------------------------------------------------------------------------
shortcut_viewer.rock--  can now call plugins rather than taking you to them
in the browser
-----------------------------------------------------------------------------
Added a new option to menus:
 F_CB_ON_SELECT_ONLY
 instead of option callback every time a item is accessed
 F_CB_ON_SELECT_ONLY fires callback only when item is selected
-----------------------------------------------------------------------------
Added manual entries
-----------------------------------------------------------------------------
