Some auto generated xlsx files are using other names as workbook than "workbook.xml".
This is fixed by supporting names of workbooks by regex `/workbook.*\.xml/`.

In cells with formulas containing conditions like `=IFSUM(A1:A3;"";B1:B3)`
to sum cells from range A1:A3 with empty value in range B1:B3, the function
`Functions::ifCondition()` create in this case the code `=""""` instead of
`=""`, so it didn't work.

We often want to export a table as an excel sheet. The system renders the
html and it seems like a waste of time to write it to the file system to
use the reader. This allows us to render the html and then just pass it to
a reader
Closes#1136
Calculation engine was resolving every function by first resolving its arguments
including IFs, this was causing significant over evaluation when IFs were used
as it meant for every case to be evaluated.
Introduce elements to identify ifs and enable better branch resolution
(pruning). We tag parsed tokens to associate a branch identifier to them.
Closes#844

Sheet titles containing " " or "!" will be quoted in formulas. This commit
fixes the lookup of sheets with this kind of title by trimming the quotes
during the lookup.
Without this any defined range referencing a sheet with " " or "!" in the title
name will be lost when reading the workbook from file.
Fixes#928
Closes 930
