Allow newline between various tags

[HoutarouOreki]

Should fix #268 for color tags.

I'll allow myself a question. How do I put regular expressions in code like this?

$text = str_replace("[i:{$this->uid}]", '<em>', $text);

Never mind, I think I figured it out myself.

Still I'm not really sure what I'm doing, just tried following the patterns. Added a function parseHeading because headings were passed in parseInlineSimple, which I made to pass multiline things, and headings shouldn't be multiline.

Also shouldn't I have renamed the "inline" function, since it now parses multiline? 🙅‍♂️🔫

Uhh, I guess for some reason there's ) instead of /color, I'm looking into this.

can just use the /s modifier for multi-line matching: /pattern/s

you don't have to merge master every other commit ಠ_ಠ

Well GitHub throws a triangle at me with an exclamation mark every time it's "out-of-date" and a big button to update it, so I thought that was the right ting to do.
