Feature: Use fzf keybindings to add additional functionality to history

[joshskidmore]

Using fzf keybindings, allow for specific history items to be removed from history list in the same manner they're selected from fzf.

Example:

• tap C-r
• use up/down/C-k/C-j to select a history entry
• use something like M-d to use fzf's execute-silent() to call a function which will delete the selected history item from the current zsh session as well as $HISTFILE
• use fzf's abort() + execute() to automatically reload updated history (with removed history item removed)

This is something I will try to tackle, but need to refresh myself on advanced zsh syntax.
