I have solved this by not centering the binary editor.
@bpasero notice that I have moved all the editor type ids from files.ts to editor.ts
Currently they were spread in those two files which felt a bit shaky to me (I might ahve introduced this initially).
Let me know if you do not like them in editor.ts and we can figure out a different way to determine the type of an editor.

@isidorn the preferences, file and binary file editor are being contributed to the workbench from vs/workbench/parts. Moving knowledge of them into editor.ts (which is a core workbench piece) is a layer breaker we should try to avoid. The following IDs should move out again:

• PREFERENCES_EDITOR_ID
• TEXT_FILE_EDITOR_ID
• FILE_EDITOR_INPUT_ID
• BINARY_FILE_EDITOR_ID

If we need to check on some property to decide to do something (like centering or not), we could have another method on editor input similar to supportsSplitEditor to answer that.

@bpasero makes sense. I have made the changes to move this back into it's appropraite layer, however now I seem to be hitting the following issue

1. Open an editor, go into center mode
2. Open preferences editor
3. Layout is called -> I need to figure out if I should center, however the preferences editor still does not have input asociated with it - it is null. Thus I can not ask the input if it supports centered editor

@isidorn you could also move this method to the BaseEditor

@bpasero yeah. Tackled via 96a741d
