heads: show closed heads only when --closed is passed

Add a --closed (-c) option to 'hg heads' to show all heads and change the
default behavior to refrain from showing fully closed branches.

Enhance 'hg heads <branch>' so that:

* default: displays normal & inactive heads, not closed heads
* --closed: displays normal, inactive & closed heads
* --active: displays only normal heads
* both --closed and --active: displays normal & closed heads only
