Please add sub-word navigation

[grylliade]

Please add sub-word navigation, i.e. "Smart caret positioning in identifiers." Looking at CDT it may be as simple as enabling an already-present option in the text editor; I'll see about figuring out enough Java to do it myself.

It you do this, please make it possible to switch it off and make sure navigation through the document is still pleasant with this switched off. I really hate when I have to press ctrl+right more than once in order to skip an identifier and go to the next token.

@grylliade , if you look into CDT sources, you can see an example of how it's done in org.eclipse.cdt.internal.ui.editor.CEditor.NavigatePreviousSubWordAction and its super classes (although that code is badly organized, I wouldn't copy it verbatim to DDT)
If you install the full CDT (or JDT) into the target platform, you can put a debug point there and see how it works in practice.

Looking further into it, it seems that DLTK's ScriptEditor already has subword navigation implemented, including an option to disable it. Is there a specific reason you're using an internal version of DLTK rather than the “official¨ version? Because otherwise it seems that just inheriting from the latest ScriptEditor will do it.

Edit: I see now from the changelog that it was for performance reasons. But is there any reason not to update the internal branch?

DDT is not using DLTK fore more than performance reasons - that's not even the main reason, but several API limitations. (You can read a bit more about here if you are interested: https://github.com/bruno-medeiros/MelnormeEclipse/blob/master/README-MelnormeEclipse.md )
