trace shutdown sometimes can't find all the functions it needs

[bobbingwide]

In certain circumstances, if 'shutdown' is invoked earlier than expected, then the logic invoked attempts to call functions that haven't been loaded.

e.g.

• bw_trace_get_hook_type( ) ( in includes/oik-actions.php),
• called by bw_trace_get_hook_links()
• called bw_trace_create_hook_links()
• called by bw_trace_count_report()
• which is invoked by 'shutdown'

bw_lazy_trace_count() should include a line to

oik_require( "includes\oik-actions.php", "oik-bwtrace" );

Oh my! I got the slash the wrong way round!

oik_require( "includes/oik-actions.php", "oik-bwtrace" );
