    Revert "language-specs: add 'text' to def.lang"
    
    This reverts commit 452af6eb8fb5b2f8345a5029a4c295fda171d617.
    
    No longer needed, latex.lang doesn't use it anymore, it was added to
    latex.lang by mistake.
    
    Other reasons include:
    - Adding things to def.lang should be done with caution, because any
      other lang file can depend on it and it can be hard to remove
      afterwards. There can also be external lang files. I don't think
      def.lang is part of the API "contract" of GSV, but still.
    
    - Normal (general) text should not be highlighted in the first place.
      The style schemes are there for changing the style/color of normal
      text.
