fix: add all necessary modes, themes to editor via annotations

[rudiejd]

Resolves https://github.com/F0rce/ace/issues/19.

• Despite being included in the jar, all of the ace build stuff was not accessible by Vaadin whenever this add-on is included in another application
• These files are necessary to make the default themes, modes work as demonstrated in https://github.com/F0rce/ace/issues/19.
• I moved all of these files to the src/main/resources/META-INF/resources/frontend folder as spec'd in the Vaadin add-on tutorial to make them accessible by applications including this addon
• Generated all the annotations for importing these and threw them on the main class

Unfortunately, I do not think there is any better syntax for including a ton of JavaScript modules. According to the Vaadin docs, you just have to use the annotation multiple times for multiple module imports :(
