Allow setting feature flags on the command line

Browse Source 
This introduces a new command line option --features which can be used for
enabling or disabling features for a particular fish session.

Examples:
  fish --features stderr-nocaret
  fish --features 3.0,no-stderr-nocaret
  fish --features all

Note that the feature set cannot be changed in an existing session.
