v1.2.0

I moved some lines of code around and, even if everything looks good, I prefer increasing the version number, just to make sure it won't break anything with existing implementation during a simple update.

In this release:

• Added svg support (thanks to @jakubfindura )
• Added special PDFMake attributes (like widths/heights for table) support using the HTML attribute data-pdfmake (see doc)
• Fixed cascaded tags inside a cell table that didn't render correctly
