o handle verbose logging in statusbar directly in statusbar code
and common code does not need any knowledge about a statusbar
o remove direct calls to statusbar_(puts|pop)_all functions
* src/folderview.c
* src/logwindow.c
* src/statusbar.c
* src/summaryview.c
only abort hook invokation if required data is missing not
if our own data pointer is NULL, update hookfunction for
log window
* src/folderview.c
* src/statusbar.c
* src/summaryview.c
* src/common/hooks.[ch]
hook functions now have a gboolean return value, if a hook
returns TRUE it will stop executing of any more hooks in
the same hooklist for this invokation
