Merge lp:~spud/spud/group-view into lp:spud

[Fraser Waters]

Allows nodes to be grouped together in the LHS hiding all other nodes.

[lp:~spud/spud/group-view]

449. By Fraser Waters on 2011-07-26

Merge from trunk.

450. By Fraser Waters on 2011-07-26

Added edit menu options. Fixed grouping on whole tree.

451. By Fraser Waters on 2011-07-26

Changed __class__ == to isinstance

452. By Fraser Waters on 2011-07-26

Choices and optionals show in group view.

453. By Fraser Waters on 2011-07-26

__str__ on Tree and Choice returns the display name.

454. By Fraser Waters on 2011-07-26

In group mode use name paths, in normal mode use display names.

455. By Fraser Waters on 2011-07-26

Refresh fix.

456. By Fraser Waters on 2011-07-26

Select the node you group or ungroup on.

457. By Fraser Waters on 2011-07-26

Grouping bug fix for choices.

458. By Fraser Waters on 2011-07-26

Fixed long names, and more choice bugs
