Accounts created using in-band registration now will use confirmation E-mail

In an effort to create a more secure method for implementing JabberIqRegister Tigase XMPP Server will now require the use of a confirmation E-mail by default in the process. The E-mail must be valid, and accounts will be made into pending status until a user clicks the generated URI in the E-mail and activates the account. This is a plugin and must be enabled in the config.tdsl file by using the following code:

'account-registration-email-validator'() {}
