Handle conflicting base interface declarations

[zspitz]

Given the following conflicting definitions between XLayoutConstrains.getMinimumSize and XTextLayoutConstrains.getMinimumSize:

interface UnoControlEdit extends UnoControl, XTextComponent, XLayoutConstrains, XTextLayoutConstrains { }
interface XLayoutConstrains {
    getMinimumSize(): Size;
}
interface XTextLayoutConstrains {
    getMinimumSize(nCols: number, nLines: number): Size;
}

the compiler gives the following error:

severity: 'Error' message: 'Interface 'UnoControlEdit' cannot simultaneously extend types 'XLayoutConstrains' and 'XTextLayoutConstrains'. Named property 'getMinimumSize' of types 'XLayoutConstrains' and 'XTextLayoutConstrains' are not identical.'

The solution is to:

• [ ] find such conflicts
• [ ] add copies of both members to the derived class; prefer members with more parameters, then members with more general parameters

[zspitz]

This algorithm is implemented, but some members were not found / cloned. For the rest, there is code that clones these methods individually.
