* Added skin credits
* Got rid of the $dir variable (and ugly PHP closing tag that isn't needed) in favor of the __DIR__ magic word
* Four spaces -> one tab for indentation
* Split the skins.custard ResourceLoader module into skins.custard (CSS part) and skins.custard.js (JS part) -- JS part should eventually have the 'position' => 'top' removed but I'm keeping it here until someone has the chance to test it out
* Fixed CSS/JS loading in the SkinCustard class; when a skin has JS, it should have its own RL module and it needs to be loaded in Skin<skinname>::initPage(), not in Skin<skinname>::setupSkinUserCss()
* Capitalized "GitHub" in an i18n message
* Added new i18n messages
* Removed warning suppression operators in the CustardTemplate class
* Parsing fix for the "Welcome to Custard Beta" dialog -- the ->plain() option means "display the text as-is", whereas here you want the ->text() option, i.e. "render the HTML in the message"
* Some other random fixes I've already forgotten about
