Migrate to Adapt

[davquar]

The Adapt intent parser is more powerful and flexible; it also doesn't have the infamous bugs of Padatious.

To migrate it should be sufficient to:

• convert the intent strings into regexes.
• appropriately tune the intent builder with require and optionally to allow both long and compact intents.

As an alternative to the last point, it is also possible to use both parsers: Adapt for compact intents and Padatious for simple ones.
