This is interesting for conferences in which they want to display, for instance, contact secretariat.

[FIX] Support email improvements

• Make the caption of the support email entry editable, both asynchronously and synchronously (new widget created for the asynchronous editing).
• User can now specify more than one email address for support email. Entries of the user are parsed and put in a valid format, both for synchronous and asynchronous editing.
• Changed the html for the support and the start/end dates entries by replacing spans by a table.
• Updated the user guide (new screenshots and small explanation about how to specify more than one mail).
• fixes #226
