Added

Show a preview of the entire command in history search (#125 - @ovv). This is very useful when dealing with long commands, which get truncated in the fzf finder; or mutli-line commands, for which the whitespace gets messed up.
The fd execution is now configurable. Users can now pass custom options to fd through the fzf_fd_opts variable. A backwards incompatible change included in this is that hidden files are no longer searched by default (#126).

Fixed

Ensure variables set by conf.d/fzf.fish are global and update uninstaller to actually uninstall everything (#122 - @etcusrvar). This was a bug for people who source fzf.fish's config file.
Remove leading underscores from fzf_search_vars_cmd, which is mean to be utilized by the end user. (f14a1d3)
