Support 3D references

[wojciechczerniak]

Description

Since we're supporting Worksheets it would be cool to support all features.

=SUM(Sheet1:Sheet4!B3)

We need to support all CRUD operations on Worksheets:

• Add sheet
• Remove sheet
• Move sheet

Rename should not have an impact on the sheet sequence.
