Give Outlook and Postbox mail tasks human-readable titles

[cygnoir]

Hi there. I just installed the Todoist Outlook extension today at work and noticed that todoist-habitrpg syncs these but the title of the task goes all wonky. If possible, I would like to request an enhancement for a future version that strips the Outlook markup from the title so it is more legible in the HabitRPG to-do list. Thank you.

Here is the data from one of mine in case it helps for testing purposes.

{
  "text": "[[outlook=id3=aWQ9MDAwMDAwMDBCOTYzOTQ4N0Y2RDQ2QTQ5OTVBMzM4QjdEMTdDQ0U2NzA3MDA1Q0I1QUY4OTNFQjYyRDRCOEVEOTQ4NkI2QURCNjlERTAwMDAwMDg4Q0Q3NzAwMDA1Q0I1QUY4OTNFQjYyRDRCOEVEOTQ4NkI2QURCNjlERTAwMDAwMEFGNTAyQjAwMDA7bWlkPTxGM0UxNERBOUM5MTQ4NzRGODQ3RjkwRDNFRkJBRkYzQzE1QjE4Q0BNRVItRVhDSDIubmFwaWVyLmFjLnVrPg==, Update doc: Procedure documents - External's access to libraries - Membership Cards]]",

  "checklist": [],
  "collapseChecklist": false,
  "completed": false,

}

ETA: the Todoist Postbox extension does the same thing, only with [[thunderbird]].

Added this to #16

I believe gmail has an extension that does something very similar.

This would be nice to add. Thanks for adding it to the formatting story @crookedneighbor
