Update time
I'd like esp. all the ones having AUTH issues to test again the two AUTH types available and report any changes.

• Fixed a phrase that didn't show in Admin's global settings
• Added admin option for the automatic addition of the "Webmail" links: "Never add any link", "Only add for users having propper permission" and "Always add selected links"
• When the mailbox is empty it no longer shows "An error accoured...", it now correctly displays a notice "Your inbox is empty" instead (this notice can be hidden completely by deleting the used phrase)
• "Empty strtotime() call" should be fixed, no longer causing that PHP warning and showing "N/A" when no or invalid date in mail specified
• Added option in user settings to choose between WYSIWYG editor and simple textbox (default is still WYSIWYG)
• Fixed a few things in inc_accessconfig.php - hopefully the warnings and SQL errors regarding the config are now gone....
• Added an experimental fix in the SMTP protocol that MIGHT raise compatibility with more SMTP server's requiring authentication
• Added option (in user settings) to be automatically redirected back to the "Write A New Mail" page after successfull sending
