CHANGED: If you set the auto-increment value to a negative number,
created a net label and hit the insert key, when the name got below zero,
the net labels tried to go negative but created bad labels instead.
Now the code caps decrementing at zero, warns users when it has
happened, and explains why.

Rotate text using the Rotate90() function which gets the orientation
right.
Also, when calculating the center point for rotation, don't include
labels if the selection contains other stuff. It just makes the
rotation odd, and tends to cause walking when continuing to rotate
(due to keep-upright being non-symmetrical).

1) Generalize SCH_ITEM owners (SCH_COMPONENT, SCH_SHEET, and now
SCH_GLOBALLABEL)
2) Generalize hypertext items
3) Use SCH_FIELD autoplace infrastructure for placing intersheet
references
4) Use textVar infrastructure for buildin intersheet references.
As an important side-effect this also fixes the undo issues with
intersheet refs.
Also improves the SNR and consistency of the menu item text. For
instance, a position is rarely useful, while relative sizes can be.
Also removes some unnecessary repitition, such as "Graphic Rectangle"
when "Rectangle" communicates the necessary information.
Set up a new lineage for SCH_ITEMS to get back to the SCHEMATIC
they live on: Items will all be parented to the SCH_SCREEN that
they are added to, and each SCH_SCREEN will point back to the
SCHEMATIC that it is part of. Note that this hierarchy is not
the same as the actual schematic hierarchy, which continues to
be managed through SCH_SHEETs and SCH_SHEET_PATHS.
Texts were drawn with a minimal line thickness = GetDefaultPenWidth().
The default pen width can be to large for small texts.
So the actual text thickness is now always clamped.
