imap-send: URI encode server folder

When trying to send a patch using 'imap-send' with 'curl' and the following configuration: [imap] folder = "[Gmail]/Drafts" host = imaps://imap.gmail.com port = 993 sslverify = false results in the following error, curl_easy_perform() failed: URL using bad/illegal format or missing URL This is a consequence of not URI-encoding the folder portion of the URL which contains characters such as '[' which are not allowed in a URI. According to RFC3986, these characters should be URI-encoded. So, URI-encode the folder before adding it to the URI to ensure it doesn't contain characters that aren't allowed in a URI.
