dupEmailCheck validation fails

[rturnes]

Hi!
I am using this component and I would like to suggest a correction.
When an email with dot is inserted (example: "roberta.t@email.com"), the dupEmailCheck validation fails.

Replace the line 109 with:
var existingElement = $list.find(".email_name[data-email='" + arr[i].toLowerCase().replace('.', '\\.').replace('@', '\\@') + "']");

Email with same text but with different case sensitive is duplicating.

Replace the line 94 with:
var arr = t.val().toLowerCase().trim().replace(/^,|,$/g , '').replace(/^;|;$/g , '');
