Nested html tags use styles of all elements in stack

[jakobjoachim]

While working on fixing Issue #432 I noticed a Bug when using nested spans with styles:

This HTML Code should produce a bold and italic text

<span style="font-weight: bold;">
    <span style="font-style: italic;">
        text
    </span>
</span>

But because only the first item in the stack is used when converting to docx the result is only italic:

<w:r>
    <w:rPr>
        <w:i/>
    </w:rPr>
    <w:t xml:space="preserve">text</w:t>
</w:r>

should be:

<w:r>
    <w:rPr>
        <w:b/>
        <w:i/>
    </w:rPr>
    <w:t xml:space="preserve">text</w:t>
</w:r>

Not sure about the COMBINED ContainerType.
Otherwise just some formatting issues.

Please revert the formatting changes in the whole file

Incnsistent formatting (whitespace around braces, curly braces in new line)

Does this implementation lead to problems in ODT when combining Paragraphs?

[jakobjoachim]

I just checked the ODTDocumentHandler.java currently it doesn't support styles from spans at all. So it really makes no difference. There is probably an Issue or there should be an Issue reading the Span Styles as well and when that is implemented the containerType would be read as well.

@MalteJoe what do you think about this PR?

@angelozerr As the Formatting Guidelines mentioned in https://github.com/opensagres/xdocreport/wiki/CodeFormatAndConvention are outdated and may be replaced with https://github.com/palantir/palantir-java-format at some point, I will close my comments regarding formatting. There's still one open comment, but it's too old for me to remember what exactly it was about, as I haven't been working with xdocreport for a while now.
