A sheetpath is required to correctly resolve text variables.
Depending on currentSheet is rife with bugs.
There are many places where we do *not* want to be prepending
field names to the field values, such as netlisting,
building PDF hypertext menus, etc.
Also, Find/Replace needs to work on unresolved text, as
that's what we're going to display (and if replace nuked
your variable references you wouldn't be happy).
EDA_ITEMs are responsible for giving their parent a crack at it if
they failed to resolve it. This recurses all the way up to the schematic/
board, and then to the project.
Cross-reference handling is also move to the EDA_ITEMs. It must be done
before bubbling up so that we don't end up in loops. (The aDepth parameter
will break the loop, but without having done anything useful.)

Shared schematics can have a root sheet instance when opened with the
schematic editor in stand alone mode. This would cause a crash when
opening the shared schematic in a project where it was shared because
the root instance was trying to be saved in the normal sheet instance
data which is not valid.

This will make it possible to maintain sheet instance information when
copying and pasting from any sheet other that the root sheet of a
project.
Setting and getting sheet page numbers must now be performed using a
sheet path. This was done to ensure that the instance paths were not
getting changed unexpectedly from different code paths.
This change reverts the storage of all symbol instance data in the root
schematic. This was done because it's not possible to reuse instance
data when importing from sub-sheets.
There has been a fundamental change in how sheet paths are store in the
instance data. The root schematic UUID is always used when saving the
instance data. To prevent file churn, the virtual root sheet UUID is set
to the root schematic UUID when loading the project. This provides a way
to determine the project that stored the instance data. All uses of paths
without root sheet have been expunged from the code.
The sheet instance data is still saved only in the root sheet for the
time being. New sheet instances will be automatically assigned an page
number based on the incremental virtual sheet page number. Sheet page
numbers will not be imported.
Added project name to instance data to improve the readability of the
schematic file format. It also creates an opportunity to remove orphaned
instance data by project name rather than cryptic UUIDs.

ID was not maintained or used other than to ensure unique fields.
Instead of saving, we assign the known IDs to specific field names and
sequentially create new IDs on load

Also moves most navigation code to SCH_NAVIGATION_TOOL.
Also changes page number href to anchor syntax ('#foo').
Also adds hypertext processing to SCH_TEXTBOXes.
Also adds combobox with schematic pages to text properties dialog.
CHANGED: The text variable ${SHEETNAME} now always represents the name of the
sheet when used anywhere in the schematic editor, including the title block
ADDED: A new text variable ${SHEETPATH} which is replaced with the path to the
current sheet - e.g. "/Sheet 1/Sheet 2".
To ensure backward compatibility, the default drawing sheet now uses
${SHEETPATH}. Custom drawing sheets will need to be manually edited.
We need to keep the screen blank while initially loading a sheet before
the hierarchy is developed. Avoid resolving text variables during this
process
