Add more logging in the debugger perspective

	* src/persp/dbgperspective/nmv-dbg-perspective.cc
	(DBGPerspective::on_debugger_bp_automatically_set_on_main): Add
	function enter/exit logs.
	(DBGPerspective::execute_program): Add more logging here.
Continue execution upon (re)start with breakpoints set

	* src/persp/dbgperspective/nmv-dbg-perspective.cc
	(DBGPerspective::execute_program): When we are (re)starting the
	inferior with breakpoints set, let's assume the user wants to
	continue the execution of the inferior upon its (re)loading; so
	let's do her that service.
Fix some comments

	* src/persp/dbgperspective/nmv-dbg-perspective.cc
	(DBGPerspective::on_debugger_breakpoints_set_signal): Fix
	comments.
Fix continue action label

	* src/persp/dbgperspective/nmv-dbg-perspective.cc
	(DBGPerspective::init_actions):  The continue action cannot be
	used to restart the inferior because it's not active when the
	target is not ready.
