Convert Todoist Text Formatting

[crookedneighbor]

Todoist has some text formatting options, some of which are actually documented. In addition to bold, italic and links, you can also highlight %(hl) foo% and underline %(u) bar%.

Markdown doesn't do underlines, I don't think, but highlighting could be used for code.

Would be great to convert bold, italic, highlighting and links from Todoist's way of doing them to markdown, so the formatting persists in Habit RPG.

Here's a checklist of things:

• Highlights %(hl) foo%
• Underlines %(u) bar%
• Links: http://google.com/ (Google)
• Italic: __Italic text__
• Bold: !!Bold text!!
• Outlook Link: [[outlook=id3=aWQ9MDAwMDAwMDBCOTYzOTQ4N0Y2RDQ2QTQ5OTVBMzM4QjdEMTdDQ0U2NzA3MDA1Q0I1QUY4OTNFQjYyRDRCOEVEOTQ4NkI2QURCNjlERTAwMDAwMDg4Q0Q3NzAwMDA1Q0I1QUY4OTNFQjYyRDRCOEVEOTQ4NkI2QURCNjlERTAwMDAwMEFGNTAyQjAwMDA7bWlkPTxGM0UxNERBOUM5MTQ4NzRGODQ3RjkwRDNFRkJBRkYzQzE1QjE4Q0BNRVItRVhDSDIubmFwaWVyLmFjLnVrPg==, Actual Text goes here]]

👍 - I like this. Especially since it can easily be tested and contained to it's own function.

Edited my comment to include a checklist, and added @cygnoir's issue about outlook from #35

Hi there. I am checking on the status of this, and wanted to add the Postbox link format too:
