Show resolution in ticket header when it is defined

[pkou at ua.fm]

When ticket header is rendered, then resolution is specified for closed tickets only.

Taking into account multiple statuses that can exist, the resolution should be displayed when it is defined regardless of current ticket status.

Patch for trunk:

 <div id="content" class="ticket">

- if:ticket.status == 'closed' ?>(Closed: <?cs var:ticket.resolution ?>)<?cs
+ if:ticket.resolution ?>(<?cs var:ticket.status ?>: <?cs var:ticket.resolution ?>)<?cs
  elif:ticket.status != 'new' ?>(<?cs var:ticket.status ?>)<?cs

Also, it makes consistent status displaying (always in lower case).

(In preparation to #869)
