getFrontMatter() invoked multiple times

[aedart]

In an attempt to design a possible cache solution (#51), I found that \Todaymade\Daux\Tree\Content::getFrontMatter() might be invoked multiple times:

• From \Todaymade\Daux\Tree\Content::getContent()
• And from \Todaymade\Daux\Tree\Content::parseAttributes()

I'm not too sure about this being a defect - But if I read the code correctly, then markdown content is parsed twice, which does have some negative effect on performance. Should getFrontMatter() not return evt. previously rendered content, if any is available?

Hello,

I made the change to call it only once.

The change doesn't give a big performance boost : https://blackfire.io/profiles/f105b698-8393-4058-8707-ea2f2b1ee69e/graph

2% is not a lot, but it's still something :)
