Subject: [PATCH] SmartArt: basic orgchart support

This is a combination of 12 commits.

SmartArt: bullet list improvements

by default start bullet list at second level
use stBulletLvl parameter to change this behaviour

SmartArt: support multiple levels of shapes in LayoutNodes

it is needed for recurrent ForEach node, so that shapes on different levels
are divided and can be layouted separately

SmartArt: support ForEach references

ForEach 'ref' parameter causes specified ForEach node to be used instead.
Used to create recursive structures like organisation charts.

now all transition arrows are created in cycle diagrams

SmartArt: move setting shape aspect ratio to alg atom visit

it allows to correctly follow if/else nodes instead of using once assigned
alg atom

SmartArt: all visitors follow data presentation nodes

* visitors now are keeping track of current presentation node instead of
  looking it up by name
* extracted visitor base class that follows if/else and for-each nodes
* moved condition logic from ConditionAtom to visitor, as it depends on
  visitor state

SmartArt: make if-node functions relative to current presentation node

* maxDepth calculates maximum depth of associated data node children
  (instead of per-diagram max depth)
* cnt counts children of associated data node (instead of looking up presOf
  node and if not found counting presentation node children)

SmartArt: remove calculateHierChildOffsetScale() from org chart algorithm

Its purpose was to center subtree if sibling parent has no children.
It was not working correctly for complex charts causing shapes to overlap.
Without it chart is still readable (just sometimes not centered).
Remove it for now until more universal solution is found.

Revert "SmartArt: support multiple levels of shapes in LayoutNodes"

As we have presentation node - shape mapping, keeping shape level information is no longer needed.

This reverts commit 596a03b65e1b870be671ea1a44f4fba9fc66e4ae.

    (taking into accout hierBranch alg variable)
  * then actual layout using that count to calculate size for subtrees

SmartArt: hide connectors in org chart as they don't work correctly

Fixing them would require a lot of effort.
Changes are needed in data part (connector shapes are not created in group
shapes associated with data shapes) and in layout part - routing them
differently in all 4 or 5 hierBranch styles, with assistants and without.
