Introduce an EShellView::execute-search signal.

This addresses bug #593896 but is also a cleaner design than before.
It introduces an EShellView::execute-search signal and renames the
"search-execute" action to "search-quick" to clarify that it's only
meant for the "quick" search bar in the main window.

Shell view subclasses should implement the execute_search() method to
actually execute a search.

e_shell_view_execute_search() emits the new signal.
