Fix issue #363 where image list toggle icon didn't show if there was only a single image (preventing one from being able to delete the image, if they happened to start in grid mode, for example).
Fix issue #365 where ProcessPageClone delivered a fatal error when trying to clone a page that lacked a 'title' field.
Attempt fix for @teppokoivula issue #367 where change tracking was not reset automatically for multi-language text fields.
Add a language-specific change to the change tracking in LanguagesPageFieldValue per issue #373
Attempt fix/addition for issue #374
Reverse update from commit #374 because it appeared to be causing major side effects.
Add a reloadLanguages method to Languages class per issue #374
Addition of a WireMailInterface and WireMail module base class to allow for 3rd party modules to replace PW's PHP-based mail() sending. Also added a wireMail() function as a replacement for PHP's mail(), but that uses whatever WireMail module is installed.
Some updates and usage instructions added to WireMail(). Also put together an example WireMail module, but will post that in the forums.
Integrate HariKT PR #366 (for reconnect to PDO db when connection lost) and Interrobang/Klickstarter PR #382 (for support of MySQL socket).
Updates to WireMail to support "to" names and some other optimizations.
