Now mbwatch will look for a group called "mbwatch" to find what channels and
mailboxes to watch. This allows the user to be move specific in what they are
watching. You don't always need to watch the "INBOX" nor do you have to watch
all of the channels you have setup in with mbsync.
The config will need to be defined in the `Channels` prop on the group. It
needs to be a comma separated of channels and mailboxes. This is an example of
the config.
```
Group mbwatch
Channels work:INBOX, work:Archive, personal:INBOX
```
Summary:
This will now support a port config in the IMAPStore of the config. This is
still optional and will fall back to 993 if you don't have it.
It will also ignore tls verification if we have a CertificateFile config
option. This will take a bit of refactoring to implement our own tls context
so, for now we will disable it. As we have put in the comment, if the user
really wants this then they can configure this in there root store.
