Adding a custom field fails with "An unexpected error"

[sofixa]

Hi,

First, great work! I've been playing around, and i seem to be unable to add a custom field from the Chrome extension(can't try it from the Web Vault because, like in #24 , objects aren't visible), it fails with "An unexpected error occurred" in the interface, and the following in the logs(running with docker-compose with one nginx, one bitwarden-go and one bitwarden-web with @leonghui 's containers):

                                                                                                                                                                           bw_back_1  | 2018/03/17 16:57:51 XXX is trying to edit his data                                                                                       bw_back_1  | 2018/03/17 16:57:51 Cipher decode errorjson: cannot unmarshal array into Go struct field newCipher.fields of type string

And it seems the reason is at https://github.com/VictorNine/bitwarden-go/blob/master/internal/api/api.go#L172

Are custom fields supported?

Cheers, Adrian

That's right these are not supported yet

I have implemented custom fields and Notes (at the moment only strings). So if you want to try it, you can use my forks master branch. I plan to submit a pull request in the next time, but as I have done major changes it is hard to make my branch compatible with VictorNines.
