v2.1.0: VI mode prompt

Changes the default behaviour of the prompt in vi mode to use ❮ whenever the user is not in insert mode. This matches the behaviour of the zsh version of Pure:

Toggling between mode using Esc and i key.

Customization

We introduce a new variable to control the symbol for reverse prompt:

pure_symbol_reverse_prompt "❮"  # used for VI mode

And a flag to control the feature:

# VI mode indicator
# true (default):  indicate a non-insert mode by reversing the prompt symbol (❮)
# false:           indicate vi mode with [I], [N], [V]  
pure_reverse_prompt_symbol_in_vimode true
