Re-group View menu so Navigation comes before Tree operations

The MEF block of the View menu used MenuOrder = 100/101 for Back/
Forward but no MenuOrder on Sort assembly list / Collapse all tree
nodes, so the latter two implicitly defaulted to 0 and ended up
appearing before Back/Forward despite their numerically larger
explicit order. The intent reads better the other way around:
Back/Forward are high-frequency keyboard-driven actions (Alt+Left/
Right) and belong adjacent to the show-radios block, while Sort and
Collapse are tree-operation bulk actions that belong further down.

Use the same non-overlapping MenuOrder ranges that File now follows:

  Navigation: 0 .. 9      (Back, Forward)
  Tree:       10 .. 19    (Sort, Collapse)
  Options:    999         (Options)

Sort and Collapse moved from MenuCategory = "View" to "Tree" because
the category identifier should describe the operand -- both act on
the assembly tree, neither is a generic "view" action.
