Unify discussion about fileeditor settings

[ellisonbg]

We have a number of other issues about the fileeditor settings. We now have a formal settings system for persisting global settings and I wanted to create a new issue that summarizes things in one place.

Here is a list of possible fileeditor settings and its current status.

• Line numbers (global setting)
• Word wrap (global setting)
• Match brackets (global setting)
• Keybinding (global setting)
• Theme (global setting)
• Tabs versus spaces (missing)
• How many spaces (missing)
• Syntax highlight language (missing)

Reality of our current approach: we don't yet have a way of having settings for languages (python, C/C++, JS, etc.) so we have to live with a simplified version of things.

Questions:

• Which of these things should be global settings versus per editor?
• Should we try to save the per editor settings (maybe by path?) or just forget when the file is closed.

Marking as beta as the lack of some of these things currently makes some file types impossible to work with in lab (Makefiles).

Fixed for now we in master.
