Better search/lookup stuff

[eritbh]

If there's no exact match for e.g. e;docs createmessage it should return the first relevant result, maybe with an "other matches" section in the result or something

• classless method search (e.g. searching editStatus would result the same as client editStatus)
• basic inclusion checking (searching for ditS would result the same as editStatus
• basic typo tolerance (editStatis --> editStatus) (+- 2ish characters) (maybe use this? https://github.com/krisk/fuse)
