Dimensionless quantities have all exponents equal to zero.
Such quantities are simply numbers. The associated unit is
the unit one, symbol 1, although this is rarely explicitly
written.
See chapter 2.3.3 Dimensions of quantities, The International
System of Units, 9th edition.
Every basic data type is stored in Base module, color is standing out as
one that does not. Moving it to Base opens possibilities to integrate it
better with the rest of FreeCAD.
Convenience helpers function Tools::toStdString and Tools::fromStdString
were implemented for Qt4 or older to perform utf8 aware conversion as
QString::toStdString/QString::fromStdString were using toAscii/fromAscii
internally (see https://dreamswork.github.io/qt4/classQString.html).
Since Qt5 QString uses toUtf8/fromUTf8, which makes the helper functions
obsolete (see https://doc.qt.io/qt-5/qstring.html#fromStdString).

No longer add dynamic property for alias, simply rely on
get(Dynamic)PropertyByName() to check for aliases.
Add new API PropertyContainer::getPropertyNamedList() so that
ExpressionCompleter can discover properties with aliases.
Make `Cell::setContent` use `unique_ptr` and
`make_unique` for expressions to avoid potential memory
leaks.
Also renames `expo` to `newExpr` to avoid mixup with the
member variable `expression`.
Both changes was made at the request of @chennes.
This commit only changes the user interaction with spreadsheet and does
not affect backwards compatibility (as valid cell expressions are
prefixed with '=' when serialized).
This fixes [#4156](https://tracker.freecadweb.org/view.php?id=4156),
which is discussed in the forum thread:
https://forum.freecadweb.org/viewtopic.php?f=3&t=39665
There has been additional logic added to handle numbers and simple
fractions without using '='.
The behaviour is what is expected by the spreadsheet test cases
and in line with how other spreadsheet software works.
The '-prefix can still be used to force the input to be handled as
as string instead.
Example of numbers and fractions handled are:
3
2mm
1/8
1mm/2
1/2mm
2/m
1mm/2s
More complex expressions are not handled without '=' and will be stored
as strings instead, for example:
2 / 3 / 2
1 + 1/3

PropertySheet is changed to derive from PropertyExpressionContainer,
which makes it a link type property that is capable of external linking.
It now relies on the unified link property API to manage object
depenency, and tracking of object life time, relabeling, etc.
This patch also includes various fix and improvement of Spreadsheet,
such as improved recompute efficiency, correct handling of document
label change, etc.
