wickeditor.js - Capitalization of shortcut variables is inconsistent

[kryptot7]

In wickeditor.js, there are several helpful variables like alertbox, menubar, and rightclickmenu that refer to UI elements. However, capitalization is inconsistent. Some variables like builtinplayer are all-lowercase, while other variables like editorSettings and editorCredits are in camelCase. I think these helper variables should be consistently in camelCase.
