* Add -a option to generate a temporary NNN_FIFO
* Add documentation for -a option
* plugins/README.md: promote the use of -a
This obsoletes the global FIFO unlink trick, so I remove mentions of it.
@jarun update:
Polish -a
* Allow launching plugins with Alt + plugin's key
* Fix Alt key in filter/prompts modes
* Fix handling Alt key in nextsel()
In filter mode: run the associated plugin.
In prompt mode: just throw out the Alt+key input.
In nextsel(): differentiate Alt+key and Esc
* Add a tabbed/xembed based file previewer plugin
This plugin is written in bash, because job control is not well
specified in POSIX sh (`jobs` can return anything).
We use `tabbed` [1] as a xembed [2] host, to have a single window
owning each previewer window.
Uses mpv, sxiv, zathura, and the nuke plugin.

* tabbed-preview: prevent focus steal with xdotool
* preview-tabbed: tabs->4 spaces
* preview-tabbed: add focus prevention timeout
* Add an option to print hovered files to a FIFO
This adds an env variable, `NNN_FIFO`, that can be set to a path that
`nnn` will open/create as a FIFO, and where every hovered file's path is
printed. This allows creating external perview/quick open plugins, ...
It can be compiled out with the make variable `O_NOFIFO`.
* Check filename ptr instead of full path (for FIFO)
* Add documentation to use NNN_FIFO in plugins
* Fix path sent to FIFO in empty dirs
Support `$_Z_DATA` environment variable per z's documentation dcd5541e7d/z.1 (L78).
`$_Z_DATA` allows changing the default location of the z database file.
* Add nvim as a diff tool for getplugs plugin
* Comment out `is_cmd_exists()`
* Add nvim diff tool for diffs plugin
* Add $EDITOR to nuke plugin for editing/reading text file format
* Modify diff command to fix CircleCI failures
* Fix getplugs prompt
* Allow nuke to use custom $PAGER
