Avoid code symbols showing up in "Jump to Symbols" HuD

[diethardsteiner]

I like to use the "Jump to Symbols" HuD to navigate the TOC of my Markdown docs. However, I realised that for certain code blocks (e.g. YAML) the symbols do actually pollute the symbol listing of the "Jump to Symbols" HuD. I am not sure if this can be controlled via this bundle or if this is actually something that has to be addressed within TextMate itself.

Unfortunately I don't have time to investigate this myself, but if someone comes up with a fix I'd be more than happy to merge it.
